Gerardo,

I think the approach used in this code should do what you want. Dorry I 
don't have time for more explanation...

Hi,

I have different questions to use tex with matplotlib.

The first one:

If I'm doing:

rc('text', usetex=True)
xlabel('$\textrm{toto}$')  # bad
xlabel(r'$\textrm{toto}$') # ok

The results are not the same and I don't understand why.

and for:

xlabel('$\textit{toto}$')  #bad
xlabel(r'$\textit{toto}$') #ok

same things, but it's working fine for:

xlabel('$\it{toto}$') #ok
xlabel(r'$\it{toto}$') #ok

but it's not working for \bf:

xlabel('$\textbf{toto}$')  # bad
xlabel(r'$\textbf{toto}$') # ok
xlabel('$\bf{toto}$')        # bad
xlabel(r'$\bf{toto}$')       # ok

And this bring to the second question, I would like to create the xlabel with 
latex stuf inside somewhere in my script:

label='$\textrm{test}_2$'

but that can't work:

xlabel(label) # bad

How to tell that I want the "r" before the chains to have TeX working like 
expected?

Thanks,

N.

Hi,

I'm trying to draw a line given an angle, magnitude, x0 and y0 
location on a 2d line plot.  I use the "cosine" and "sine" to find 
the x1 and y1 locations so that I can draw a line segment from x0, y0 
to x1, y1.  This works fine on a 200 x 200 (Width x Height) pixel 
graph.   However, I have an input form where the user can change the 
plot size, for example 200x800 or 800x200.

The "magnitude" is along the y-axis and "time" is along the x-axis. 
At a particular point in time the magnitude and angle is given and I 
have to calculate the x1 and y1 values.  The max magnitude along the 
y-axis (height) is always the same whether it is 200 pixels in height 
or 800 pixels in height.

The scientist I'm working with wants to see the magnitude (x1,y1) of 
each plot look correct if the graph is 800 pixels or 200 pixels in 
height.   He also wants the correct angle if you stretch the graph 
from 200 pixels wide to 800 pixels wide and then down to 100 pixels 
wide.

I've been trying to use a ratio of the graph size to maintain the 
correct sizing but with no luck.   Basically, the scientist want to 
maintain the same angle and reduce or increase the magnitude in the 
y-axis if the graph height is reduced or increased.

Does anyone have an answer to this solution?  Maintaining the same 
angle and varying the magnitude based on the y-axis height.

Since, I have a lot of points I started to use a LineCollection to 
speed the rendering speed.

Maybe, there is a connection, but I don't quite understand how it would
come.

Ticks are rendered as linemarkers. They are not filled, so, in the new
version, markeredgecolor should follow the line color automatically. If
you set the line color to white, the tick color should also become white.

Could you send along your matplotlibrc and specify in detail how to
reproduce the problem?

Actually, I don't care (tremendously) if I have to wait 'til after it's 
drawn to get the info (I've already found other instances where, to do 
what I've wanted, I've had to draw, then get/modify/set then redraw - as 
you say, inelegant, but serviceable; it's not like the old days where 
re-drawing meant waiting half a minute) so if that info is available 
after the figure's been drawn, that's good enough for me (as long as 
it's possible to set it as well as get it) for now.  Is that what 
legendPatch.get_window_extent().get_bounds() does?  (I'll probably find 
out using dir before you reply, but a reply would be appreciated anyway, 
so the info will be in the archive).

I'm getting closer to the point where I feel like I might be capable of 
doing this, but I'm not quite there yet. :-)

This is closer to my confidence level.

Ah, so it looks like it does make sense for the user to specify an 
alignment, and have it figured out at draw time.

That does seem the way to go. David, I've done stuff like this for the 
wxPython FloatCavnas -- perhaps I can help, if you want to do it.

Please keep posting your experiences.
At work I'm about to spend my first ever time on a Mac,
and I expected this to be a blessing,
but such reports worry me!

Again, afraid not.  At least nothing obvious.  The legend placement is
done dynamically at draw time, and so it will be difficult to get this
information ahead of time.  There might be some cleverness that can be
applied, but nothing easy.

One option would be connect to the draw event, and then inspect the
legend properties, and then place it where you want knowing the width
and the height.  Not too elegant, but serviceable.  Here is an 
untested sketch


def ondraw(event):
    if ondraw.done: return 
    # in pixels
    left,bottom,width,height = leg.legendPatch.get_window_extent().get_bounds()
    # move your legend....
    ondraw.done = True
ondraw.done = False    

fig = figure()
ax = fig.add_subplot(111)
leg = ax.legend(blah)
fig.canvas.mpl_connect('draw_event', ondraw)


It might be better to patch legend directly to do what you want and
send the patch our way.  Or subclass it.

OK, I was afraid of that; in that case, is there some way to get the 
height and width of the legend (so I can do what I want 
programatically)?  Thanks again,

Stephen,

On the dev list was an ANN post which stated that 0.87.7:

This release is compiled against numpy-1.0 final.  The binaries are
fresh on sourceforge, so they may take some time to propagate to the
mirrors.

http://cheeseshop.python.org/pypi/matplotlib/
http://sourceforge.net/project/showfiles.php?group_id=80706&package_id=82474

Note: There is a compile error on python2.3 that will probably require
a slight modification to the released source.  Please allow some time
for us to fix this and post the binaries.

I wrote a plotting module for matplotlib that can be used with Boa or easily
integrated into your own wxPython application.

If you are interested in the plugin, pls. send e-mail to kh...@in....

like Times as the serif font and Helvetica as the sans-serif are the
magic combination for Miktex-2.5.  I can make any other fonts work
with true type fonts and usetex: true.

Thanks Darren.  type1cm got installed on the fly by miktex the first
time I ran this, but that must not have taken effect fast enough or
something.  The miktex package manager now shows it as installed and
deleting my matplotlib tex.cache and ttfont.cache and re-running my
test leads to the usual, beautiful results (without changing the
default fonts).

Thank again,

Ryan

You could try changing your font settings in matplotlibrc, maybe times for 
serif and helvetica for sans-serif. dvipng is trying to locate a font that 
hasn't been (or cannot be) generated. This is usually an issue with bitmapped 
fonts, which are generated on demand, so you would get lots of these messages 
when working with a new Miktex install. 

I dont know why bitmapped fonts are being used though, since usetex 
specifically asks for type1 fonts. Maybe you need to go into your miktex 
package manager and make sure you have type1cm available on your system.

  C++, typename is a reserved word there.

  That is the solution, and you say the same that was adopted by the

I am trying to use latex with matplolib on Windows XP with MikTex 2.5
and dvipng 1.8.

I am getting this warning:
dvipng warning: font cmsy10 at 512 dpi not found, characters will be left blank

when I do this:

t=arange(0,1,0.01)
y=sin(2*pi*t)
plot(t,y)

and this
ylabel('$y(t)$')

leads to
dvipng warning: font cmr17 at 356 dpi not found, characters will be left blank

with no ylabel.

I am also getting a lot of other output (see below).

How do I fix this?

Thanks,

Ryan

The error is not in matplotlib, it is in a pygtk header file, which is 
presumably coming from a Redhat package.  I don't know why it is 
happening or what the best solution is, though.  It looks like the 
pygobject.h that I have has "typename_", not "typename", so I am 
thinking maybe this is a pygtk bug, since fixed, in which "typename" is 
in conflict with something.  You might try editing your copy of 
pygobject.h, adding the trailing underscore to "typename" on both lines 
where it occurs.  It can't hurt; these are just dummy variable names.

Thanks for the support.

I uninstalled numarray, and then compiled/installed most recent numpy and 
matplotlib from the tarballs.

And I am happy to announce I can now perform the mundane task of plotting 
barcharts and histograms. :)

Thanks again everyone,
Suresh

	Hi all,

	I am trying to build Matplotlib 0.87.7 on an RHEL 4.4-derived system, 
with Python 2.3.4. I am running into a weird problem. When I do "python 
setup.py build", I get the following error:

gcc: src/_gtkagg.cpp
In file included from /usr/include/python2.3/Python.h:8,
                  from /usr/include/pygtk-2.0/pygobject.h:5,

before "typename"



	So I did a google search, and found someone recommending that "#include 
<Python.h>" be prepended to the offending file. I have prepended it to 
src/_gtkagg.cpp, did a clean, and run the build again. The error 
changed, and the "_POSIX_C_SOURCE" problem went away, but the build is 
still failing, at that same file:

gcc: src/_gtkagg.cpp
In file included from src/_gtkagg.cpp:11:
/usr/include/pygtk-2.0/pygobject.h:140: error: expected `,' or `...' 
before "typename"

In file included from src/_gtkagg.cpp:11:

before "typename"
/usr/include/pygtk-2.0/pygobject.h:147: error: expected `,' or `...' 
before "typename"



	Does anyone have an idea of what is going wrong here? I could really 
use some help, as I am totally stumped.

	Many thanks in advance.

Yes, both are mandriva packages:

python-matplotlib-0.87.4-2mdv2007.0
python-numarray-1.5.2-1mdv2007.0

Given there isnt a python-numpy package for x64-64 right now (there is a 
devel one, so not sure why no main package), I will go ahead and try to 
build from scratch.

Thanks,
Suresh

Yes I noticed that 0.87.6 is available from fedora-extras for FC6. But
unfortunately this one is unable to work with numpy 1.0 final. But
thanks nonetheless ;).
And as Chuck pointed out - he managed to compile from svn. I tried the
new 0.87.7 and that one finally compiled.
I ran some quick tests and it seems to work well.
So thanks for your help @Chuck,Trond.
