[Matplotlib-users] ytick fontsize for exponentials
Hi matplotlib users
I am trying to fit a substantial number of subplots into a single plot.
I would therefore like to reduce the font size of my x- and yticks. Some
of the plots contain very large numbers on the y-axis. Using the default
formatting this means that the exponential will be written above the
plot. When the font size of the y-axis is reduced the font size of the
exponential above the plot is not reduced as shown in the example code
below:
import pylab
pylab.figure()
x = [1, 2, 3]
y = [1e13, 2e13, 3e13]
pylab.plot(x,y)
pylab.xticks(fontsize=6)
pylab.yticks(fontsize=6)
pylab.savefig('test.png')
Has anyone got any suggestions on how to reduce the font size of the
exponential as well or is this a bug in matplotlib?

Re: [Matplotlib-users] Wanted: recommendations on embedding matplotlib in a wxPython application
I may be jumping into this conversation way too late, but I really
like wxmpl. The one bell and whistle that I love is the
click-and-drag box zoom available by default. Attached is my hacked
together simple example of putting a wxmpl.PlotPanel on a wx.notebook.

This is all straightforward and clear. The one statement I've not yet
understood is this:
self.graph = matplotFrame3.PlotPanel(self.panel1 ,xpoints,
ypoints)
I assume that matplotFrame3 is the name of the module in which you've
written PlotPanel(). Is this assumption correct?
Exactly. That is the module which I mention importing in step 4.
I'm modifying your approach to suit our application but it seems to be
the
most parsimonious and elegant solution for simple display of plots in a
wxPython panel.
Thanks,
Glad it will help your application.

[Matplotlib-users] wxmpl: Can't create printer PDF because the id PDF is already used
I just created a small wxmpl example that I really like (attached),
but when I run it, I get these error messages:
** (python:18091): WARNING **: Can't create printer PDF because the
id PDF is already used
(python:18091): GnomePrintCupsPlugin-WARNING **: The CUPS printer PDF
could not be created
(python:18091): GnomePrintCupsPlugin-WARNING **: The data for the CUPS
printer PDF could not be loaded.
I don't know if this is wxmpl specific, caused by wxPython, or caused
by matplotlib, but I would like to make it go away. Any thoughts?
Thanks,
Ryan
