matplotlib-users Mailing List for matplotlib (Page 9)

Well the thread on the devel list that I referred to explicitly has the
win32 exe in its title ("Missing __init__.py in
matplotlib-0.87.5.win32-py2.4.exe ?") . The starting post there pretty
much says it all.
There's also a recent post on the numpy list that sounds like it's maybe
the same problem (quote):
"""
Is there a compatible matplotlib as well? I was o.k. with mpl from
enthought until I switched numerix to numpy. That made mpl unhappy.
I downloaded 0.87.5 but I broke something in the process because now
even switching back to Numeric doesn't make mpl happy.

Hello,
I'm creating a program that plots data in real-time. I want the
x-axis to be the time in HH:MM:SS. I'm still playing with the date
formatters, but have run into a problem where it seems the axis puts
in more points on the axis to make the plot fit nicely. For instance,
I want to have 120 data points (seconds) on the graph. Initially, the
x-axis starts at, say 0 and goes to 120 (I'd expect this to be 119).
The following second the x-axis should go from 1 to 120, then 2 to
121, etc. But instead, the x-axis goes from 0 to 140. Once 141
seconds have passed by, the axis shifts and goes from 20 to 160.
Is there any way to make the axis behave so that it keeps just 120
values on the axis and increment the values as described above?
Thanks!
-Roberto.

Thank you! I realized later how to do this when I realized that I 
hadn't looked at the code for the canvases.

I tend to think not. You put 80,000 points in a PS, it's going to be 
big. That's all there is to it, it's the nature of Postscript.
I do think clipping is a good idea though.
What is the maximum precision in Postscript? It seems unlikely that you 
could plot 80,000 points and not have number of them overlap, unless 
it's clipped, so removing essentially redundant points may be another 
way to to go.

FWIW, I've had very good luck recently using inkscape
(http://www.inkscape.org/) to edit PS files, both old ones made by
who-knows-what and fresh mpl-off-svn ones. I've been able to fix old
labels that needed changes for figures whose data source is nowhere to
be found, change a line color and dashing/cap style, etc. I'm not a
graphics artist and have never used Illustrator, but for my needs,
inkscape has so far been an excellent (and free!) solution.
Note that this is on a Linux Ubuntu Dapper box, with the pstoedit
program installed, which inkscape uses to read *PS files into an
editable vector format.
Cheers,

One of these days, we'll have to figure out how to embed individual glyphs 
rather than the entire font set.

I keep running into the ImportError problem described on the devel list,
with the win32 2.4 binary (exe). Is that still just a case of waiting
for the mirrors to update, or is there a deeper problem? Are there
alternative download links? How to tell whether it's the "right" binary,
since version numbers are the same?
Thanks for your help,
Sven

Well, the fonts are correct -- I checked in both the EPS source, and 
what Illustrator thinks the font is (after translation with pstopdf).
The definition of the fonts looks right in the EPS source (checked by 
comparing against a sample from illustrator).
If nobody else is having the same problem, typing pstopdf is really 
not a tremendous burden. I just thought I would raise this issue.
BTW, SVG files seem to do fine with fonts. However, it can take a 
very long time to save large files in MPL and import large files into 
Illustrator, which seems to want to translate them into some native 
format, and does so poorly.
If I ever figure out a better solution, I'll let you all know,

Another things that can be good to add is a better clipping. For the moment=
=20
there are no clipping that means if I have something like::
x =3D arange(1000)
plot(x,x)
xlim(30,40)
savefig('test.svg')
All the point are stored in the file, not only the part between 30 and 40.
This is something I spoke before and I fill a bug or feature request on=20
sourceforge (I'have been unable to find it today but I looked fast).
You can check the problem with the svg created if you open it with inkscape=
,=20
you'll see all the point. I understood that this is a bug inside inkscape t=
oo=20
butthat means that all the point are there and it's a big concern for me wh=
en=20
I have to plot plenty of spectra and use only a small range because I know=
=20
that my file at the end will be huge. The only way I found is 1) save in pn=
g=20
and use another software to save it in eps but I loose the fact that eps is=
 a=20
vectoriel format 2) do the clipping myself or 3) create my plot with anothe=
r=20
software like pgplot or gnuplot.=20

Good idea. Should we make it a kwarg or an rc parameter? The number of rc 
parameters continues to grow...

We could make the fmt string for PS and SVG output floats a
configurable parameter and be done with it. As you know, we've spent
a lot of time trying to get the right string that doesn't produce
visual errors and I'm not inclined to change the default. But we
could make it an rc param for those who want to trade accuracy for
space.

Are you sure you have set the font paths properly *and* flushed your
~/.matplotlib/ttffont.cache before regenerating your files. Use
--verbose-debug when creating your test EPS to make sure you are
getting bitstream fonts. If you still have trouble, post an errant
eps file somewhere and maybe someone can poke into it.

I think this is debatable, as it is a closed source implementation of
an open document format specification. But I am willing to accept
that it is more likely that Illustrator is right than that mpl is
right.

matplotlib embeds the truetype fonts directly into the postscript
file, so what you see on the screen is what you get in the ps file.
This is a feature and not a bug :-). The file size ocst is fixed and
does not grow with plot size. If you find these largish PS files
unpalatable, you can use native postscript fonts by setting
ps.useafm : True # use of afm fonts, results in small files
in your matplotlibrc file -- http://matplotlib.sf.net/matplotlibrc

Each data point consists of a line like 
54.3869 28.6788 l
which is 17 bytes long. 17*80000 = 1.36MB. Maybe we dont need as many sig

I have been having problems with postscript output from MPL on my 
various Macs that is just beyond the problem discussed in the tread 
here. But this seemed like the best place to bring it up. The basic 
problem is that Adobe products like Illustrator can't read MPL .eps 
output.
When I 'Open' the file, OS X uses ghostscript to convert the EPS to 
PDF, and this displays fine. I can use Preview to save this file, 
and it looks alright, however, none of the Adobe products can read 
the PDF either. Usually the file will open, but the fonts are all 
screwed up.
When I use pstopdf from teTeX (but *not* epstopdf -- that doesn't 
work for some strange reason), then I can open my new PDF file in 
illustrator.
I think that opening an EPS in Illustrator is the ultimate test of 
EPS format compliance, as those are the folks who made it. What can 
we do to make MPL output universally readable postscript?
-Rob
p.s. One I finally do get it into Illustrator, it becomes clear that 
MPL makes very nice, efficient, easily editable files... unlike 
MATLAB. For me this is yet another big reason to switch to python/ 
numpy/mpl.

Is there a method of using the show() command more
than once in a script? I know that it should be
called once all commands have been entered for the
graph, but I'm wondering if there is a way of
resetting this so that I can call show() a second time
without my program crashing.
Thanks,
Matt

Hi,
The following plot
>>> from numarray import *
>>> x = arange(80000)
>>> from pylab import plot,show
>>> plot(x,x)
>>> show()
and saving in postscript format generated a file of 1.5MB, while the equivalent is 
only 288KB in xmgrace (another plotting program). If I use plot(x,x,"k,"), this
even leads to a horrible 8.0MB. How come? I understand there is an issue 
with the fonts, but this can't be the only responsible, can it? Plotting no points, 
just a title, and saving in postscript leads to a file size of only 133KB.
FWIW, I'm trying to make postscript plots using Python 2.4.1, latest numarray, 
and matplotlib 0.83.2.

VS2003.Net is needed to easily build the python 2.4 version. (e.g.
python setup.py build) You can also follow the mingw instructions for
a more open-source way of building matplotlib for windows. We still
have to do this for python 2.3. You can supposedly download the .net
compiler tools for free, but I haven't tried. I am pasting my
previous post since I didn't re-all.

Karl,
This was fixed some time ago with completely new colorbar code, 
including a change in the API. Attached are a modification of your test 
program to suit the API (and make a smaller png file for this email), 
and the result.
