matplotlib-users Mailing List for matplotlib

more information on this. if i try to use pdf.use14corefonts, like was
suggested by Jouni, as follows:
from scipy import *
import matplotlib
matplotlib.use('PDF')
from matplotlib import rc
import matplotlib.pyplot as plt
rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})
rc('pdf', use14corefonts=True)
then when i open the generated pdf in adobe illustrator i get the error:
"The font "Helvetica-Narrow" contains a bad /BBox." -- then no labels are
shown in the graph, only the nontextual elements.

Can anyone help me out? I'm trying to do the following equivalent in a scatter3d call...
line, = ax.plot(data1, data2)
line.set_data(data3, data4)
line.axes.figure.canvas.draw()
So I'm looking to do:
ax = axes3d.Axes3D(fig)
s = ax.scatter(data1, data2, data3)
s.set_data(data2,data3,data4) <-- but this function doesn't exist... what is the equivalent that I'm missing?
s.axes.figure.canvas.draw()
TIA

hi all,
I am not sure if I have helvetica installed as a TTF -- how can i install it
if i don't?
i followed the debug suggestion and here are the results. when i set the
font to arial, using:
from matplotlib import rc
rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})
then the relevant output i get using --verbose-debug is:
matplotlib version 0.98.5.2
Using fontManager instance from /Users/perf/.matplotlib/fontList.cache

I think the issue here is to connect points in two different axes,
which is possible but can be a bit difficult.
In the svn version of matplotlib, there are some helper classes to
ease this job a bit.
I'm attaching the example.
I think you can also run the example with 0.98.5.3. Just download
inset_locator.py and modify your import statement.

One more precision : my intent is to draw a figure 'statically', I do
not need event handling, ie handling manual zoom through an interactive
backend. The figure is generated from a script and directly saved

I have been wondering the same issue whether Chaco's nice zoom plot
could be made possible in Matplotlib. I don't have an answer for this
yet. If you come up with one, please let me know.
In the mean time, you can take a look at: http://www.simile-widgets.org/
They have some interesting and eye-catching time-series plots for
web-demonstrations.

Yes, I can reproduce this with the current svn.
I think what's happening is that, with larger number of grid, there
is slight overlapping between each subplots (likely due to the
floating point error). Note that subplot command deletes existing axes
if they overlap with the new one.
There would be several work-arounds. You may use non-zero spacing, eg,
0.001 worked for me. Or, you may manually add subplots to the figure
to avoid any deletion of existing axes.
from matplotlib.axes import Subplot
fig = gcf()
subplots_adjust(hspace=0.,wspace=0.)
for i in xrange(1,65):
 ax = Subplot(fig, 8, 8, i)
 fig.add_subplot(ax)
 plot( [0,1] )

Hi, I'm trying to make a large grid of subplots with no spacing between. The
following code fails for any grid size larger than 6x6 by skipping a row and
a column.
for i in xrange(1,65):
 subplot(8,8,i)
 plot( [0,1] )
 subplots_adjust(hspace=0,wspace=0)
Is there a way around this problem?
Thanks,
Adam

Thanks to point to this scikit, but I looked into the lib.plotlib
module, and I didn't manage to find something looking like the 'zoom
effect' Chaco provides...
I merely wanted to add a Polygon patch between the upper and the lower
subplots, but using data coordinates from these axes.

oh, I knew about set_{x,y,}data() but I actually though I had to feed it

It's clear enough in the examples :)
maybe the doc should be a bit more verbose?

You can refer to animation examples [1] for code that does what you want.
[1] http://matplotlib.sourceforge.net/examples/animation/index.html
at the very end, you update the line data with set_ydata() ,
set_xdata() or set_data() and then call a draw() on the figure.

Are you certain you have Helvetica installed as a TrueType font? If you 
don't, the only way to get the Postscript Helvetica is to set 
"ps.useafm" to True.

Hello everybody,
I wonder whether it is possible to produce something like the zooming
plot example from http://code.enthought.com/projects/chaco/gallery.php
using only matplotlib. I've done some tests, I think transforms may be
helpful but I do not know ho to use them...

Hi list
I've been asked to transform my app to something more "dynamic"
it currently reads an xml file, it has now to read a stream of xml from
a socket (I can handle this part :D) and plot each point as they are
coming from the network.
I'll end up having tons of points over multiple axes; I guess doing
sonething like fig.plot(concat(old-data,new-point)) would be rather
inefficient and I wonder if someone ever made something like this using
matplotlib?
or any hints on where to start from?
thanks :)

It might be in a format that matplotlib doesn't really handle. However,
Helvetica is one of the "core fonts" in PDF so if you set
pdf.use14corefonts to True, you should be able to use Helvetica, and the
reader application will supply the font (or approximate it with
something else). This is deprecated in the latest version of the spec,
but it should work just fine.

The font-selection system is somewhat complicated. I suggest running
your script with --verbose-debug with both Arial and Helvetica as the
value of font.sans-serif, and diffing the outputs to see what is going
on. I suspect that Arial is a TTF file while Helvetica is in some
Mac-specific format. The best solution would be to make matplotlib
handle those formats, but probably the most practical solution is to
use something like fondu to convert the font into TTF:

I am pleased to announce that the Python Software Foundation is
sponsoring 10 students' travel, registration, and accommodation for
the SciPy 2009 conference (Aug. 18-23). The focus of the conference
is both on scientific libraries and tools developed with Python and on
scientific or engineering achievements using Python. If you're in
college or a graduate program, please check out the details here:
http://conference.scipy.org/student-funding
About the conference
--------------------
SciPy 2009, the 8th Python in Science conference, will be held from
August 18-23, 2009 at Caltech in Pasadena, CA, USA. The conference
starts with two days of tutorials to the scientific Python tools.
There will be two tracks, one for introduction of the basic tools to
beginners, and one for more advanced tools. The tutorials will be
followed by two days of talks. Both days of talks will begin with a
keynote address. The first day’s keynote will be given by Peter
Norvig, the Director of Research at Google; while, the second keynote
will be delivered by Jon Guyer, a Materials Scientist in the
Thermodynamics and Kinetics Group at NIST. The program committee will
select the remaining talks from submissions to our call for papers.
All selected talks will be included in our conference proceedings
edited by the program committee. After the talks each day we will
provide several rooms for impromptu birds of a feather discussions.
Finally, the last two days of the conference will be used for a number
of coding sprints on the major software projects in our community.
For the 8th consecutive year, the conference will bring together the
developers and users of the open source software stack for scientific
computing with Python. Attendees have the opportunity to review the
available tools and how they apply to specific problems. By providing
a forum for developers to share their Python expertise with the wider
commercial, academic, and research communities, this conference
fosters collaboration and facilitates the sharing of software
components, techniques, and a vision for high level language use in
scientific computing.
For further information, please visit the conference homepage:

Previously the Mac OS X backend indeed used its own machinery to create PDF files. Recent versions of the backend in SVN, however, use matplotlib's pdf backend. So the problem should go away if you use matplotlib from SVN.
The Mac OS X backend itself can actually be fixed to use vector graphics on screen instead of bitmaps. That will need some time, but I'll get round to it one of these weeks.
