matplotlib-users Mailing List for matplotlib (Page 15)

I have rebulit from SVN. It turns out that my problem only happens
with really large fonts. I am using Darren's new font size
specification with font.size =3D 18 or 24 and
everything else set to medium or large:
axes.titlesize : large # fontsize of the axes title
axes.labelsize : medium # fontsize of the x any y labels
xtick.labelsize : medium # fontsize of the tick labels
ytick.labelsize : medium # fontsize of the tick labels
legend.fontsize : medium
(I really like that new size scheme Darren.)
with font.size =3D 18, things are o.k. with 24, they are clipped on the
screen, in the pdf, and even a little in the png.
This may be closely related to what Steve just posted.

Hi
1)
Using the recent svn version I get axes labels which are partially cut 
off when using mathtext (*no* usetex) and increasing the font size (see 
attached "image_cut.png"):
rcParams['xtick.labelsize'] = 18
rcParams['ytick.labelsize'] = 18
rcParams['axes.labelsize'] = 18
plot([1,2,3])
xlabel(r'$\rm{value}\ \sum\prod\Omega x_i$')
ylabel('y-Titel')
savefig("image_cut.png")
I observed this with .png, jpg and .eps
2)
Is it possible for the "\Omega" in "image_omega.png" to be upright (like 
it would be for usetex=True) and not inclined?
rcParams['xtick.labelsize'] = 18
rcParams['ytick.labelsize'] = 18
rcParams['axes.labelsize'] = 18
plot([1,2,3])
xlabel(r'$\Omega$')
ylabel('y-Titel')
savefig("image_omega.png")
cheers,
steve

I cant reproduce your problem using the most recent checkout from svn. How 
does your eps file look, does the problem only exist in the pdf?
Darren

I have a small problem when saving figures with
savefig.facecolor : gray #white # figure facecolor when saving
savefig.edgecolor : gray #white # figure edgecolor when saving
set in my rc file.
If I run
t=3Darange(0,1,0.1)
y=3Dsin(2*pi*t)
plot(t,y)
xlabel('Time (sec)')
ylabel('amplitude')
savefig('gray.eps')
and then epstopdf gray.eps, I get the attached file with the gray
border not going quite low enough. This doesn't occur when saving
.png. It also seems to be o.k. if I just use xlabel('time') without
the parenthesis and uppercase T.
I am including the figures in a Latex beamer presenation with a dark
background and I need the gray border for visability.
I tried switching to gs-8.50, but the problem didn't do away. I am
using version 0.86.2 which is probably cvs from a month ago.

Hello,
Is there a way to specify that a legend show its items
horizontally instead of vertically, i.e.:
x-x-x-x label1 y-y-y-y label2 z-z-z-z label3
vs.
x-x-x-x label1
y-y-y-y label2
z-z-z-z label3
?
Thanks,
Gerald

This is just a shot in the dark, but I've been playing with pycairo a 
bit, and found that you need to make sure to call:
cairo.Context.show_page()
When you're done with the rendering. I had similar symptoms before I did 
that.
John,
What are your plans regarding Cairo and the future of rendering for MPL? 
I'm in the need of alpha blended rendering for wxPython stuff, so I've 
been looking at Cairo and Agg. Agg is a great solution for really nice 
rendering, but Cairo has the promise of supporting everything else I 
need, like PDF for instance.
Now that Mozilla seems to be adopting Cairo, it might even live up to 
the promise of a fully cross-platform solution. If so, it would be great 
to develop a really general purpose, robust, numpy-aware, pythonic 
interface for it.

Hi all,
I've only started using matplotlib very recently, and it's hugely
impressive. My current plotting is (occasionally) failing with the
error copied below (Fedora Core 4 standard install, Python 2.4...).
Does anyone know what causes this and whether I can tell from the data
being plotted whether it might happen? Sorry if that's a dumb
question, but ....
Many thanks!
Sarah

Hi everyone
When looking at the little code example below
it can be seen see that you have to mix programming
paradigms to disable autoscaling:
 figure(1)
 ax = subplot(111)
 axis((-0.25,2.0,0.0,1.3))
 axis('scaled')
 ax.set_autoscale_on(False)
Wouldn't another 'axis' option make the
whole thing more consistent?
 figure(1)
 axis((-0.25,2.0,0.0,1.3))
 axis('scaled')
 axis(autoscale=False)
Best regards,
Nikolai

Yes, you want to use the pylab axes function
 http://matplotlib.sourceforge.net/matplotlib.pylab.html#-axes
which allows you to place an axes anywhere. Still uses relative
coords, but your arithmetic will be *much easier* than it was for
subplots. Eg where leftrel is the relative left border and leftin is
the left border in inches, you can compute letfrel (which is what axes
wants) with 
 leftrel = leftin / figwidth

Right, it's just a special case helper function. Here is a screenshot

I agree. It would be nice to be able to pass in units of your choice,
inches, points, cm, relative, pixel, data for all locations. You can
do this relatively easy for some datatypes (eg lines, text, etc) by
using custom transforms, but not everywhere (eg axes positions are
always relative).

You are welcome to work on this. I think it would be a nice
addition. You might want to start by looking at the Axis code for
example to see how the xlabel and ylabel position are chosen to not
overlap the tick labels, as an example of how to work with the
matplotlib bounding boxes. This kind of stuff will be essential for
your layout algorithms.

Hi,
I'm not sure whether my previous mail has really reached the mailing 
list or not. Excuse me if it is posted twice.
Currently I have written a wrapper script that allows me to set all 
types of margins in inches instead of relative coordinates:
width -- the width of the figure in inches
height -- the height of the figure in inches
margins -- a list of margins [left, right, bottom, top] in inches
spacing -- a list containing the horizontal and the vertical spacing
 between the subplots.
pylab.gcf().set_figsize_inches(width, height)
all_axes_width = (width - margins[0] - margins[1])
axes_width = (all_axes_width - (pylab.gca().numCols - 
1)*spacings[0])/pylab.gca().numCols
all_axes_height = (self.height - margins[2] - margins[3])
axes_height = (all_axes_height - (pylab.gca().numRows - 
1)*spacings[1])/pylab.gca().numRows
pylab.subplots_adjust(
 left=margins[0]/width,
 right=1-margins[1]/width,
 bottom=margins[2]/height,
 top=1-margins[3]/height,
 wspace=spacings[0]/axes_width,
 hspace=spacings[1]/axes_height
)
I wonder if their is a cleaner way of doing this, without a wrapper 
function? Is it possible to organize multiple axes in a plot in another 
way than using the pylab.subplot function?
I'm currently preparing a publication for which the plots are created 
with matplotlib, and I would like to share some of my experiences. The

_.get_rgb() is a mistake, I've changed it to gc.get_rgb().
Using the latest cairo (git), pycairo (cvs) and matplotlib (svn) and
running examples/simple_plot.py I get a 22K PDF file. But when I try to
view it with evince and xpdf I get "unable to open document" type
errors.
The matplotlib cairo PDF backend relies on the cairo PDF backend.
The cairo PDF backend is relatively new, and is still being developed,
and I believe it currently only supports a limited set of fonts.

No, you found a bug. I have fixed it, but it may take me a little while 
to get it committed to svn--this will be my first commit since the

I will send another message shortly.

pcolor doesn't seem to be using the vmin and vmax values that I supply
to it. If I do:
X,Y = meshgrid(arange(-2,2,.1), arange(-2,2,.1))
pcolor(X**2 + Y**2, vmin = 1., vmax=2.)
I see a smooth paraboloid (ie, without the min/max clipping in the
center on the edge that I would expect).
However, if I instead do:
imshow(X**2 + Y**2, vmin = 1., vmax=2.)
I see what I expect, a circular dark region, surrounded by a smoothly
varying ring, surrounded by a white area to the edge of the plot. 
I'm using OS X 10.4.5, Python 2.3.5, and matplotlib 0.87. Am I doing
something wrong?

What is the status of the cairo pdf backend? I installed it, but got a =
python error at line 257 of backend_cairo.py.
_.get_rgb() doesn't make sense to me, so I changed it to gc.get_rgb(). =
 Now everything runs without error, but the generated pdf file is 42Mb =
even for a simple plot. And there is a font problem.

Hi Antoine,
I had exactly the same problem. I tracked it and found that in the=20
setupext.py, when I tried to print the module.library_dirs variable after t=
he=20
command:
module.library_dirs.extend([o.tcl_lib, o.tk_lib])
I got:
['/usr/share/tcl/tcl8.4/../', u'/usr/share/tcl/tk8.4/../']
The string containing the tk library path is a unicode one for some reason =
I=20
do not understand. I changed then the line which fills this string. It is i=
n=20
the function find_tcltk(): of setupext.py:
o.tk_lib =3D os.path.join(tk.getvar('tk_library'), '../')
I replaced it by:
o.tk_lib =3D os.path.join(str(tk.getvar('tk_library')), '../')
And that did the trick.
I really don't understand why the tcl library string is not affected by the=
=20
same problem anyway...

Whatever you set to '/usr/lib/tk8.4/../' needs to be a list
['/usr/lib/tk8.4/../'] and not a string.
