matplotlib-users Mailing List for matplotlib

Not exactly OT.

I would not recommend using .eps format in order to
export MPL graphs for Inkscape.  I've been playing
around with Inkscape for a few days now and I've been
using .svg exclusively and don't have any problem.  

As I said before, I like the fact that once I am
inside Inscape, I can do an ungroup of the graph, and
work with all of the plotting elements individually. 
In fact, I just discover a nice way to "cut and paste"
a particular subplot over to PowerPoint.  This gives
me very high quality graphs in Power Point (I can
scale all I want).  No more fuzzy, ugly-looking Power
Point charts.  

Here's how:

a) Create MPL plots in .svg format
b) From Inscape, read in .svg
c) Select subplot and ungroup
d) Copy and paste to a new page 
e) Shrink the page down to the size of the object
f) Save as emf file
g) Import into PowerPoint  

In addition, I am also using Inscape to get around the
problem with the PDF backend in MPL.  I reported
previously that I am unable to save more then 8 PDF
files per execuation.  Now, I save the files in .svg
format, then invoke Inscape in command line mode and
export the file in pdf format.   Works great.

Regards,

As far as I'm concerned, being unsupported disqualifies the feature from being 
included in mpl.

I think we're just going to build on Intel. Most things will be Universal, but
scipy won't.

We're looking at moving our stuff to wx 2.8 in the near term, so probably that.

What's the plan with:

  - PPC vs. Intel -- has someone figured out how to make Universal 
binaries from Fortran?

  - wxPython versioning -- though if you go with 2.8+ you should be able 
to keep that easy. If you need some wxPython/MPL testing -- let me know,

I'd *really* like the ability to ``usepackage`` for various reasons and it
would clearly add useful functionality that is not otherwise obtainable.

I understand concern about an additional support burden, but couldn't this be
handled by explicitly noting that it's unsupported, possibly even printing out
an unsubtle warning like so:

warnings.warn("""

Not anymore it isn't. We are in the process of building eggs for the Mac, though.

That could be, I'm using GPL ghostscript 8.54.

I am not in favor of adding a parameter that allows users to add additional 
lines to the preamble. It took a lot of work to get usetex working on all 
platforms, and I just don't have the kind of time anymore to add an option 
that will allow endless configuration of latex parameters. It's not the 
implementation of the patch that is the problem, it is all the support 
requests that will follow from latex-specific failures related to customized 
preamble settings.

I just tried it with xpdf distiller (didn't know about that option before)
and it works fine! So ghostscript seems to be the problem. I use
ghostscript-esp 8.15.4, maybe there is some incompatibility there?

Anyway, for me the problem is fixed. Thanks a lot!

No problems here. I'm using the same version of latex that you are. Fonts 
render correctly with both the ghostscript (default) and xpdf distiller 
options.

Hi List,

my rendered latex fonts do not get displayed correctly when I use font sizes
smaller than 10. I use linux with the following latex version:
pdfeTeX 3.141592-1.30.5-2.2 (Web2C 7.5.5)

When integrating the eps in my latex script the font inside the plots
consists just of small vertical lines instead of the text. When I use a font
size larger or equal than 10 the text gets displayed correctly. The problem
seems to be font-family independent.

Where could be the problem? Matplotlib, latex? Does someone has the same
problem?

Here is some example code, it is from the matplotlib cookbook with the font
size changed which produces a plot with scrambled text:

import pylab
from pylab import arange,pi,sin,cos,sqrt
fig_width_pt = 246.0  # Get this from LaTeX using \showthe\columnwidth
inches_per_pt = 1.0/72.27               # Convert pt to inch
golden_mean = (sqrt(5)- 1.0)/2.0         # Aesthetic ratio
fig_width = fig_width_pt*inches_per_pt  # width in inches
fig_height = fig_width*golden_mean      # height in inches
fig_size =  [fig_width,fig_height]
params = {'backend': 'ps',
          'axes.labelsize': 8,
          'text.fontsize': 8,
          'xtick.labelsize': 8,
          'ytick.labelsize': 8,
          'text.usetex': True,
          ' figure.figsize': fig_size}
pylab.rcParams.update(params)
# Generate data
x = pylab.arange(-2*pi,2*pi,0.01)
y1 = sin(x)
y2 = cos(x)
# Plot data
pylab.figure(1)
pylab.clf()
pylab.axes([0.125, 0.2 ,0.95-0.125,0.95-0.2])
pylab.plot(x,y1,'g:',label='$\sin(x)$')
pylab.plot(x,y2,'-b',label='$\cos(x)$')
pylab.xlabel('$x$ (radians)')
pylab.ylabel('$y$')

Hi,

Please search the list.  The questions came up 2 or 3 times over the 
last year or so.

Good luck,

In the matplotlib-users list archive, I noticed that someone once
mooted the possibility of patching the matplotlib LaTeX code to
provide a user-configurable parameter that would allow one to add
extra lines to the LaTeX preamble. I didn't see any responses from the
matplotlib developers regarding their opinions of the suggested patch,
however.

Hi List,

my rendered latex fonts do not get displayed correctly when I use font sizes
smaller than 10. I use linux with the following latex version:
pdfeTeX 3.141592-1.30.5-2.2 (Web2C 7.5.5)

When integrating the eps in my latex script the font inside the plots

seems to be font-family independent.

Hello list -

I am trying to use FancyArrow to draw an arrow with given length.
The length I use is from 0 to 100.
I specify length_includes_head=True.
This works fine when I specify a width and length.
But when I specify an overhang, the length of the arrow becomes much longer
than 100.
Am I using overhang incorrectly?
Here's a script with the problem:

from pylab import *
from matplotlib.patches import FancyArrow
axis([0,120,0,100])
ax = gca()
a = FancyArrow( 0, 40, 100, 0, length_includes_head=True, head_width=5,
head_length=5)
ax.add_patch(a)
b = FancyArrow( 0, 60, 100, 0, length_includes_head=True, head_width=5,
head_length=5, overhang=5)
ax.add_patch(b)
draw_if_interactive()

Thanks, Mark

It seems like it would be a relatively easy thing for a Novice mode to be
added to the Enstaller.  The novice mode would just show you three happy
buttons: install, upgrade, and uninstall.  Under the hood it would be
picking some particular set of packages for you.  In fact even for experts
it would be nice if there were some buttons that would select a sane set of
standard packages from the list.  There was just way too much stuff there
the last time I tried it.  I also had trouble telling what it was actually
doing so I just went back to easy_install from the command line.

Er,  but this is probably a discussion for an enthought mailing list, not
matplotlib...

Hello list -

I want to run mpl interactively from IDLE on Windows XP.
For that I need to use the '-n' option when starting IDLE.

However, in the recent version of Python, when I select the IDLE icon and
right click to set the properties, the 'target' is now grey and cannot be
edited.
In the past I could edit the target and add the '-n' option.
Not anymore.

Any ideas how to change this?

Thanks,

Mark

Thanks for the pointer to the new egg installer of Enthought.
Nice app, which I will use.

But this is, IMHO, not what we need to move the python/numpy/scipy/mpl combo
into the more mainstream use.
Many potential users won't know what to do with the long list of packages
that they have never heard of.
I think it would be very useful to have one installer that gets a reasonable
distrubtion installed (like the old Enthought installer).
Isn't something like that in the works for the Mac?
We can even make a python/numpy/scipy/mpl and then a seperate one that also
includes ipython and wxpython, for example.

Or maybe a webpage where you can just select what eggs to install.
Would that be doable?
Anybody else think this is what we need?

Mark

Not at present, no.
