New entries should be added at the top
2005-06-06 Added autoscale_on prop to axes
2005-06-06 Added Nick's picker "among" patch - JDH
2005-06-05 Fixed a TeX/LaTeX font discrepency in backend_ps. - DSD
2005-06-05 Added a ps.distill option in rc settings. If True, postscript
output will be distilled using ghostscript, which should trim
the file size and allow it to load more quickly. Hopefully this
will address the issue of large ps files due to font
definitions. Tested with gnu-ghostscript-8.16. - DSD
2005-06-03 Improved support for tex handling of text in backend_ps. - DSD
2005-06-03 Added rc options to render text with tex or latex, and to select
the latex font package. - DSD
2005-06-03 Fixed a bug in ticker.py causing a ZeroDivisionError
2005-06-02 backend_gtk.py remove DBL_BUFFER, add line to expose_event to
try to fix pygtk 2.6 redraw problem - SC
2005-06-01 The default behavior of ScalarFormatter now renders scientific
notation and large numerical offsets in a label at the end of
the axis. - DSD
2005-06-01 Added Nicholas' frombyte image patch - JDH
2005-05-31 Added vertical TeX support for agg - JDH
2005-05-31 Applied Eric's cntr patch - JDH
2005-05-27 Finally found the pesky agg bug (which Maxim was kind
enough to fix within hours) that was causing a segfault in
the win32 cached marker drawing. Now windows users can get
the enormouse performance benefits of caced markers w/o
those occasional pesy screenshots. - JDH
2005-05-27 Got win32 build system working again, using a more recent
version of gtk and pygtk in the win32 build, gtk 2.6 from
http://www.gimp.org/~tml/gimp/win32/downloads.html (you
will also need libpng12.dll to use these). I haven't
tested whether this binary build of mpl for win32 will work
with older gtk runtimes, so you may need to upgrade.
2005-05-27 Fixed bug where 2nd wxapp could be started if using wxagg
backend. - ADS
2005-05-26 Added Daishi text with dash patch -- see examples/dashtick.py
2005-05-26 Moved backend_latex functionality into backend_ps. If
text.usetex=True, the PostScript backend will use LaTeX to
generate the .ps or .eps file. Ghostscript is required for
eps output. - DSD
2005-05-24 Fixed alignment and color issues in latex backend. - DSD
2005-05-21 Fixed raster problem for small rasters with dvipng -- looks
like it was a premultipled alpha problem - JDH
2005-05-20 Added linewidth and faceted kwarg to scatter to control
edgewidth and color. Also added autolegend patch to
inspect line segments.
2005-05-18 Added Orsay and JPL qt fixes - JDH
2005-05-17 Added a psfrag latex backend -- some alignment issues need
to be worked out. Run with -dLaTeX and a *.tex file and
*.eps file are generated. latex and dvips the generated
latex file to get ps output. Note xdvi *does* not work,
you must generate ps.- JDH
2005-05-13 Added Florent Rougon's Axis set_label1
patch
2005-05-17 pcolor optimization, fixed bug in previous pcolor patch - JSWHIT
2005-05-16 Added support for masked arrays in pcolor - JSWHIT
2005-05-12 Started work on TeX text for antigrain using pngdvi -- see
examples/tex_demo.py and the new module
matplotlib.texmanager. Rotated text not supported and
rendering small glyps is not working right yet. BUt large
fontsizes and/or high dpi saved figs work great.
2005-05-10 New image resize options interpolation options. New values
for the interp kwarg are
'nearest', 'bilinear', 'bicubic', 'spline16', 'spline36',
'hanning', 'hamming', 'hermite', 'kaiser', 'quadric',
'catrom', 'gaussian', 'bessel', 'mitchell', 'sinc',
'lanczos', 'blackman'
See help(imshow) for details, particularly the
interpolation, filternorm and filterrad kwargs
2005-05-10 Applied Eric's contour mem leak fixes - JDH
2005-05-10 Extended python agg wrapper and started implementing
backend_agg2, an agg renderer based on the python wrapper.
This will be more flexible and easier to extend than the
current backend_agg. See also examples/agg_test.py - JDH
2005-05-09 Added Marcin's no legend patch to exclude lines from the
autolegend builder
plot(x, y, label='nolegend')
2005-05-05 Upgraded to agg23
2005-05-05 Added newscalarformatter_demo.py to examples. -DSD
2005-05-04 Added NewScalarFormatter. Improved formatting of ticklabels,
scientific notation, and the ability to plot large large
numbers with small ranges, by determining a numerical offset.
See ticker.NewScalarFormatter for more details. -DSD
2005-05-03 Added the option to specify a delimiter in pylab.load -DSD
2005-04-28 Added Darren's line collection example
2005-04-28 Fixed aa property in agg - JDH
2005-04-27 Set postscript page size in .matplotlibrc - DSD
2005-04-26 Added embedding in qt example. - JDH
2005-04-14 Applied Michael Brady's qt backend patch: 1) fix a bug
where keyboard input was grabbed by the figure and not
released 2) turn on cursor changes 3) clean up a typo
and commented-out print statement. - JDH
2005-04-14 Applied Eric Firing's masked data lines patch and contour
patch. Support for masked arrays has been added to the
plot command and to the Line2D object. Only the valid
points are plotted. A "valid_only" kwarg was added to the
get_xdata() and get_ydata() methods of Line2D; by default
it is False, so that the original data arrays are
returned. Setting it to True returns the plottable points.
- see examples/masked_demo.py - JDH
2005-04-13 Applied Tim Leslie's arrow key event handling patch - JDH
=================================================================
0.80 released
2005-04-11 Applied a variant of rick's xlim/ylim/axis patch. These
functions now take kwargs to let you selectively alter only
the min or max if desired. Eg xlim(xmin=2) or
axis(ymax=3). They always return the new lim. - JDH
2005-04-11 Incorporated Werner's wx patch -- wx backend should be
compatible with wxpython2.4 and recent versions of 2.5.
Some early versions of wxpython 2.5 will not work because
there was a temporary change in the dc API that was rolled
back to make it 2.4 compliant
2005-04-11 modified tkagg show so that new figure window pops up on
call to figure
2005-04-11 fixed wxapp init bug
2005-04-02 updated backend_ps.draw_lines, draw_markers for use with the
new API - DSD

2005-03-19 Reverted wxapp handling because it crashed win32 - JDH
2005-03-18 Add .number attribute to figure objects returned by figure() - FP
===========================================================================
2005-03-18 0.73 released
2005-03-16 Fixed labelsep bug
2005-03-16 Applied Darren's ticker fix for small ranges - JDH
2005-03-16 Fixed tick on horiz colorbar - JDH
2005-03-16 Added Japanses winreg patch - JDH
2005-03-15 backend_gtkagg.py: changed to use double buffering, this fixes
the problem reported Joachim Berdal Haga - "Parts of plot lagging
from previous frame in animation". Tested with anim.py and it makes
no noticable difference to performance (23.7 before, 23.6 after)
- SC
2005-03-14 add src/_backend_gdk.c extension to provide a substitute function
for pixbuf.get_pixels_array(). Currently pixbuf.get_pixels_array()
only works with Numeric, and then only works if pygtk has been
compiled with Numeric support. The change provides a function
pixbuf_get_pixels_array() which works with Numeric and numarray and
is always available. It means that backend_gtk should be able to
display images and mathtext in all circumstances. - SC
2005-03-11 Upgraded CXX to 5.3.1
2005-03-10 remove GraphicsContextPS.set_linestyle()
and GraphicsContextSVG.set_linestyle() since they do no more than
the base class GraphicsContext.set_linestyle() - SC
2005-03-09 Refactored contour functionality into dedicated module
2005-03-09 Added Eric's contourf updates and Nadia's clabel functionality
2005-03-09 Moved colorbar to figure.Figure to expose it for API developers
- JDH
2005-03-09 backend_cairo.py: implemented draw_markers() - SC
2005-03-09 cbook.py: only use enumerate() (the python version) if the builtin
version is not available.
Add new function 'izip' which is set to itertools.izip if available
and the python equivalent if not available. - SC
2005-03-07 backend_gdk.py: remove PIXELS_PER_INCH from points_to_pixels(), but
still use it to adjust font sizes. This allows the GTK version of
line_styles.py to more closely match GTKAgg, previously the markers
were being drawn too large. - SC
2005-03-01 Added Eric's contourf routines
2005-03-01 Added start of proper agg SWIG wrapper. I would like to
expose agg functionality directly a the user level and this
module will serve that purpose eventually, and will
hopefully take over most of the functionality of the
current _image and _backend_agg modules. - JDH
2005-02-28 Fixed polyfit / polyval to convert input args to float
arrays - JDH
2005-02-25 Add experimental feature to backend_gtk.py to enable/disable
double buffering (DBL_BUFFER=True/False) - SC
2005-02-24 colors.py change ColorConverter.to_rgb() so it always returns rgb
(and not rgba), allow cnames keys to be cached, change the exception
raised from RuntimeError to ValueError (like hex2color())
hex2color() use a regular expression to check the color string is
valid - SC
2005-02-23 Added rc param ps.useafm so backend ps can use native afm
fonts or truetype. afme breaks mathtext but causes much
smaller font sizes and may result in images that display
better in some contexts (eg pdfs incorporated into latex
docs viewed in acrobat reader). I would like to extend
this approach to allow the user to use truetype only for
mathtext, which should be easy.
2005-02-23 Used sequence protocol rather than tuple in agg collection
drawing routines for greater flexibility - JDH
===========================================================
2005-02-22 0.72.1 released
2005-02-21 fixed linestyles for collections -- contour now dashes for
levels <0
2005-02-21 fixed ps color bug - JDH
2005-02-15 fixed missing qt file
2005-02-15 banished error_msg and report_error. Internal backend
methods like error_msg_gtk are preserved. backend writers,
check your backends, and diff against 0.72 to make sure I
did the right thing! - JDH
2005-02-14 Added enthought traits to matplotlib tree - JDH
===========================================================
2005-02-14 0.72 released

2005-02-11 matshow fixes for figure numbering, return value and docs - FP
2005-02-09 new zorder example for fine control in zorder_demo.py - FP
2005-02-09 backend renderer draw_lines now has transform in backend,
as in draw_markers; use numerix in _backend_agg, aded small

2005-02-05 Added some default key press events to pylab figures: 'g'
toggles grid - JDH
2005-02-05 Added some support for handling log switching for lines
that have nonpos data - JDH
2005-02-04 Added Nadia's contour patch - contour now has matlab
compatible syntax; this also fixed an unequal sized contour
array bug- JDH
2005-02-04 Modified GTK backends to allow the FigureCanvas to be resized
smaller than its original size - SC
2005-02-02 Fixed a bug in dates mx2num - JDH

2005-01-20 Made some changes to the contour routine - particularly
region=1 seems t fix a lot of the zigzag strangeness.
Added colormaps as default for contour - JDH
2005-01-19 Restored builtin names which were overridden (min, max,
abs, round, and sum) in pylab. This is a potentially
significant change for those who were relying on an array
version of those functions that previously overrode builtin
function names. - ADS
2005-01-18 Added accents to mathtext: \hat, \breve, \grave, \bar,
\acute, \tilde, \vec, \dot, \ddot. All of them have the
same syntax, eg to make an overbar you do \bar{o} or to
make an o umlaut you do \ddot{o}. The shortcuts are also
provided, eg: \"o \'e \`e \~n \.x \^y - JDH
2005-01-18 Plugged image resize memory leaks - JDH
2005-01-18 Fixed some mathtext parser problems relating to superscripts

2005-01-07 Add patch from Stephen Walton to fix bug in pylab.load()
when the % character is included in a comment. - ADS
2005-01-07 Added markerscale attribute to Legend class. This allows
the marker size in the legend to be adjusted relative to
that in the plot. - ADS
2005-01-06 Add patch from Ben Vanhaeren to make the FigureManagerGTK vbox a
public attribute - SC
====================================================================
2004-12-30 Release 0.70
2004-12-28 Added coord location to key press and added a
examples/picker_demo.py
2004-12-28 Fixed coords notification in wx toolbar - JDH
2004-12-28 Moved connection and disconnection event handling to the
FigureCanvasBase. Backends now only need to connect one
time for each of the button press, button release and key
press/release functions. The base class deals with
callbacks and multiple connections. This fixes flakiness
on some backends (tk, wx) in the presence of multiple
connections and/or disconnect - JDH
2004-12-27 Fixed PS mathtext bug where color was not set - Jochen
please verify correct - JDH
2004-12-27 Added Shadow class and added shadow kwarg to legend and pie
for shadow effect - JDH
2004-12-27 Added pie charts and new example/pie_demo.py
2004-12-23 Fixed an agg text rotation alignment bug, fixed some text

2004-12-22 Fixed colorbar bug which caused colorbar not to respond to
changes in colormap in some instances - JDH
2004-12-22 Refactored NavigationToolbar in tkagg to support app
embedding , init now takes (canvas, window) rather than
(canvas, figman) - JDH
2004-12-21 Refactored axes and subplot management - removed
add_subplot and add_axes from the FigureManager. classic
toolbar updates are done via an observer pattern on the
figure using add_axobserver. Figure now maintains the axes
stack (for gca) and supports axes deletion. Ported changes
to GTK, Tk, Wx, and FLTK. Please test! Added delaxes - JDH
2004-12-21 Lots of image optimizations - 4x performance boost over
0.65 JDH
2004-12-20 Fixed a figimage bug where the axes is shown and modified
tkagg to move the destroy binding into the show method.

True and False from cbook which I erroneously thought was
needed for python2.2 - JDH
2004-12-14 Finished porting doc strings for set introspection.
Used silent_list for many get funcs that return
lists. JDH

======================================================================
2004-12-13 0.65 released - JDH
2004-12-13 colors.py: rgb2hex(), hex2color() made simpler (and faster), also
rgb2hex() - added round() instead of integer truncation
hex2color() - changed 256.0 divisor to 255.0, so now
'#ffffff' becomes (1.0,1.0,1.0) not (0.996,0.996,0.996) - SC
2004-12-11 Added ion and ioff to pylab interface - JDH
2004-12-11 backend_template.py: delete FigureCanvasTemplate.realize() - most
backends don't use it and its no longer needed
backend_ps.py, backend_svg.py: delete show() and
draw_if_interactive() - they are not needed for image backends
backend_svg.py: write direct to file instead of StringIO
- SC
2004-12-10 Added zorder to artists to control drawing order of lines,
patches and text in axes. See examples/zoder_demo.py - JDH
2004-12-10 Fixed colorbar bug with scatter - JDH

mpl_disconnect. Added a "test_disconnect" command line
parameter to coords_demo.py JTM
2004-12-04 Fixed some legend bugs JDH
2004-11-30 Added over command for oneoff over plots. Eg over(plot, x,
y, lw=2). Works with any plot function.
2004-11-30 Added bbox property to text - JDH
2004-11-29 Zoom to rect now respect reversed axes limits (for both
linear and log axes). - GL
2004-11-29 Added the over command to the matlab interface. over
allows you to add an overlay plot regardless of hold
state. - JDH
2004-11-25 Added Printf to mplutils for printf style format string
formatting in C++ (should help write better exceptions)

to kwargs - JDH
2004-11-23 backend_gtk.py: added a default exception handler - SC
2004-11-18 backend_gtk.py: change so that the backend knows about all image
formats and does not need to use IMAGE_FORMAT in other backends - SC
2004-11-18 Fixed some report_error bugs in string interpolation as
reported on SF bug tracker- JDH
2004-11-17 backend_gtkcairo.py: change so all print_figure() calls render using
Cairo and get saved using backend_gtk.print_figure() - SC
2004-11-13 backend_cairo.py: Discovered the magic number (96) required for
Cairo PS plots to come out the right size. Restored Cairo PS output
and added support for landscape mode - SC

visualization - JDH
2004-11-11 Added rgrids, thetragrids for customizing the grid
locations and labels for polar plots - JDH
2004-11-11 make the Gtk backends build without an X-server connection - JV
2004-11-10 matplotlib/__init__.py: Added FROZEN to signal we are running under
py2exe (or similar) - is used by backend_gtk.py - SC
2004-11-09 backend_gtk.py: Made fix suggested by maffew@cat.org.au
to prevent problems when py2exe calls pygtk.require(). - SC
2004-11-09 backend_cairo.py: Added support for printing to a fileobject.
Disabled cairo PS output which is not working correctly. - SC
==============================================================
2004-11-08 matplotlib-0.64 released
2004-11-04 Changed -dbackend processing to only use known backends, so
we don't clobber other non-matplotlib uses of -d, like -debug.
2004-11-04 backend_agg.py: added IMAGE_FORMAT to list the formats that the
backend can save to.
backend_gtkagg.py: added support for saving JPG files by using the
GTK backend - SC
2004-10-31 backend_cairo.py: now produces png and ps files (although the figure
sizing needs some work). pycairo did not wrap all the necessary
functions, so I wrapped them myself, they are included in the
backend_cairo.py doc string. - SC
2004-10-31 backend_ps.py: clean up the generated PostScript code, use
the PostScript stack to hold itermediate values instead of
storing them in the dictionary. - JV
2004-10-30 backend_ps.py, ft2font.cpp, ft2font.h: fix the position of
text in the PostScript output. The new FT2Font method
get_descent gives the distance between the lower edge of
the bounding box and the baseline of a string. In
backend_ps the text is shifted upwards by this amount. - JV
2004-10-30 backend_ps.py: clean up the code a lot. Change the
PostScript output to be more DSC compliant. All
definitions for the generated PostScript are now in a
PostScript dictionary 'mpldict'. Moved the long comment
about drawing ellipses from the PostScript output into a
Python comment. - JV
2004-10-30 backend_gtk.py: removed FigureCanvasGTK.realize() as its no longer
needed. Merged ColorManager into GraphicsContext
backend_bases.py: For set_capstyle/joinstyle() only set cap or
joinstyle if there is no error. - SC
2004-10-30 backend_gtk.py: tidied up print_figure() and removed some of the
dependency on widget events - SC
2004-10-28 backend_cairo.py: The renderer is complete except for mathtext,
draw_image() and clipping. gtkcairo works reasonably well. cairo
does not yet create any files since I can't figure how to set the
'target surface', I don't think pycairo wraps the required functions
- SC
2004-10-28 backend_gtk.py: Improved the save dialog (GTK 2.4 only) so it
presents the user with a menu of supported image formats - SC
2004-10-28 backend_svg.py: change print_figure() to restore original face/edge
color
backend_ps.py : change print_figure() to ensure original face/edge
colors are restored even if there's an IOError - SC
2004-10-27 Applied Norbert's errorbar patch to support barsabove kwarg
2004-10-27 Applied Norbert's legend patch to support None handles
2004-10-27 Added two more backends: backend_cairo.py, backend_gtkcairo.py
They are not complete yet, currently backend_gtkcairo just renders
polygons, rectangles and lines - SC
2004-10-21 Added polar axes and plots - JDH
2004-10-20 Fixed corrcoef bug exposed by corrcoef(X) where X is matrix
- JDH
2004-10-19 Added kwarg support to xticks and yticks to set ticklabel
text properties -- thanks to T. Edward Whalen for the suggestion
2004-10-19 Added support for PIL images in imshow(), image.py - ADS
2004-10-19 Re-worked exception handling in _image.py and _transforms.py
to avoid masking problems with shared libraries. - JTM
2004-10-16 Streamlined the matlab interface wrapper, removed the
noplot option to hist - just use mlab.hist instead.

this problem
2004-09-20 Added toolbar2 message display for backend_tkagg. JTM
2004-09-17 Added coords formatter attributes. These must be callable,
and return a string for the x or y data. These will be used
to format the x and y data for the coords box. Default is
the axis major formatter. Eg
# format the coords message box
def price(x): return '$%1.2f'%x
ax.format_xdata = DateFormatter('%Y-%m-%d')
ax.format_ydata = price
2004-09-17 Total rewrite of dates handling to use python datetime with
num2date, date2num and drange. pytz for timezone handling,
dateutils for spohisticated ticking. date ranges from
0001-9999 are supported. rrules allow arbitrary date
ticking. examples/date_demo*.py converted to show new
usage. new example examples/date_demo_rrule.py shows how
to use rrules in date plots. The date locators are much
more general and almost all of them have different
constructors. See matplotlib.dates for more info.
2004-09-15 Applied Fernando's backend __init__ patch to support easier
backend maintenance. Added his numutils to mlab. JDH
2004-09-16 Re-designated all files in matplotlib/images as binary and
w/o keyword substitution using "cvs admin -kb *.svg ...".
See binary files in "info cvs" under Linux. This was messing
up builds from CVS on windows since CVS was doing lf -> cr/lf
and keyword substitution on the bitmaps. - JTM
2004-09-15 Modified setup to build array-package-specific extensions
for those extensions which are array-aware. Setup builds
extensions automatically for either Numeric, numarray, or
both, depending on what you have installed. Python proxy
modules for the array-aware extensions import the version
optimized for numarray or Numeric determined by numerix.
- JTM
2004-09-15 Moved definitions of infinity from mlab to numerix to avoid
divide by zero warnings for numarray - JTM

--------------------------------------------
This is the Old, stale, never used changelog
2002-12-10 - Added a TODO file and CHANGELOG. Lots to do -- get
crackin'!
- Fixed y zoom tool bug
- Adopted a compromise fix for the y data clipping problem.
The problem was that for solid lines, the y data clipping
(as opposed to the gc clipping) caused artifactual
horizontal solid lines near the ylim boundaries. I did a
5% offset hack in Axes set_ylim functions which helped,
but didn't cure the problem for very high gain y zooms.
So I disabled y data clipping for connected lines . If
you need extensive y clipping, either plot(y,x) because x
data clipping is always enabled, or change the _set_clip
code to 'if 1' as indicated in the lines.py src. See
_set_clip in lines.py and set_ylim in figure.py for more
information.
2002-12-11 - Added a measurement dialog to the figure window to
measure axes position and the delta x delta y with a left
mouse drag. These defaults can be overridden by deriving
from Figure and overrriding button_press_event,
button_release_event, and motion_notify_event,
and _dialog_measure_tool.
- fixed the navigation dialog so you can check the axes the
navigation buttons apply to.
2003-04-23 Released matplotlib v0.1
2003-04-24 Added a new line style PixelLine2D which is the plots the
markers as pixels (as small as possible) with format
symbol ','
Added a new class Patch with derived classes Rectangle,
RegularPolygon and Circle
2003-04-25 Implemented new functions errorbar, scatter and hist
Added a new line type '|' which is a vline. syntax is
plot(x, Y, '|') where y.shape = len(x),2 and each row gives
the ymin,ymax for the respective values of x. Previously I
had implemented vlines as a list of lines, but I needed the
efficientcy of the numeric clipping for large numbers of
vlines outside the viewport, so I wrote a dedicated class
Vline2D which derives from Line2D
2003-05-01
Fixed ytick bug where grid and tick show outside axis viewport with gc clip
2003-05-14
Added new ways to specify colors 1) matlab format string 2)
html-style hex string, 3) rgb tuple. See examples/color_demo.py
2003-05-28
Changed figure rendering to draw form a pixmap to reduce flicker.
See examples/system_monitor.py for an example where the plot is
continusouly updated w/o flicker. This example is meant to
simulate a system monitor that shows free CPU, RAM, etc...
2003-08-04
Added Jon Anderson's GTK shell, which doesn't require pygtk to
have threading built-in and looks nice!
2003-08-25
Fixed deprecation warnings for python2.3 and pygtk-1.99.18
2003-08-26
Added figure text with new example examples/figtext.py
2003-08-27
Fixed bugs i figure text with font override dictionairies and fig
text that was placed outside the window bounding box
2003-09-1 thru 2003-09-15
Added a postscript and a GD module backend
2003-09-16
Fixed font scaling and point scaling so circles, squares, etc on
lines will scale with DPI as will fonts. Font scaling is not fully
implemented on the gtk backend because I have not figured out how
to scale fonts to arbitrary sizes with GTK
2003-09-17
Fixed figure text bug which crashed X windows on long figure text
extending beyond display area. This was, I believe, due to the
vestigial erase functionality that was no longer needed since I
began rendering to a pixmap
2003-09-30 Added legend
2003-10-01 Fixed bug when colors are specified with rgb tuple or hex
string.
2003-10-21 Andrew Straw provided some legend code which I modified
and incorporated. Thanks Andrew!
2003-10-27 Fixed a bug in axis.get_view_distance that affected zoom in
versus out with interactive scrolling, and a bug in the axis text
reset system that prevented the text from being redrawn on a
interactive gtk view lim set with the widget
Fixed a bug in that prevented the manual setting of ticklabel
strings from working properly
2003-11-02 - Do a nearest neighbor color pick on GD when
allocate fails
2003-11-02
- Added pcolor plot
- Added MRI example
- Fixed bug that screwed up label position if xticks or yticks were
empty
- added nearest neighbor color picker when GD max colors exceeded
- fixed figure background color bug in GD backend
2003-11-10 - 2003-11-11
- major refactoring.
* Ticks (with labels, lines and grid) handled by dedicated class
* Artist now know bounding box and dpi
* Bounding boxes and transforms handled by dedicated classes
* legend in dedicated class. Does a better job of alignment and
bordering. Can be initialized with specific line instances.
See examples/legend_demo2.py
2003-11-14 Fixed legend positioning bug and added new position args
2003-11-16 Finsihed porting GD to new axes API
2003-11-20 - add TM for matlab on website and in docs
2003-11-20 - make a nice errorbar and scatter screenshot
2003-11-20 - auto line style cycling for multiple line types
broken
2003-11-18 (using inkrect) :logical rect too big on gtk backend
2003-11-18 ticks don't reach edge of axes in gtk mode --
rounding error?
2003-11-20 - port Gary's errorbar code to new API before 0.40
2003-11-20 - problem with stale _set_font. legend axes box
doesn't resize on save in GTK backend -- see htdocs legend_demo.py
2003-11-21 - make a dash-dot dict for the GC
2003-12-15 - fix install path bug
