642 lines (421 with data), 23.2 kB
New entries should be added at the top
==============================================================
2004-09-28 Added save to file object for agg - see
examples/print_stdout.py
2004-09-24 Reorganized all py code to lib subdir
2004-09-24 Fixed axes resize image edge effects on interpolation -
required upgrade to agg22 which fixed an agg bug related to
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
2004-09-09 Added axhline, axvline, axhspan and axvspan

--------------------------------------------
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
