There are a few ways to make ticks invisible.

ax = subplot(111, frame_on=False)
ax.xaxis.set_ticks_position("none")
ax.yaxis.set_ticks_position("none")

If you do not mind the output size slightly adjusted, try

 savefig("somename.png", bbox_inches="tight")

You mean removing the the axes frame?

  subplot(111, frame_on=False)

I'm sorry but it is not clear what you want.

Try setting

fig.subplots_adjust(bottom=0.2)

The default is 0.1

Hi,

I am trying to generate some pngs without using the GUI interface using the
AGG backend. The problem is when I set figsize, the bottom part of the
x-axis label is clipped. I am using python 2.5 in windows XP. I just
installed the lastest version of matplotlib today version 0.98.3. Below is
the code that produces two images that both have this problem.

from matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas
from matplotlib.figure import Figure

fname1=r'C:\Documents and Settings\CCM\Desktop\test_plot1.png'
fname2=r'C:\Documents and Settings\CCM\Desktop\test_plot2.png'

fig = Figure(figsize=(4,3))
canvas = FigureCanvas(fig)
ax = fig.add_subplot(111)
ax.set_clip_box(None)
ax.plot([1,2,3])
ax.set_title('hi mom')
ax.grid(True)
ax.set_xlabel('time')
ax.set_ylabel('volts')
print fig.get_size_inches()
canvas.print_figure(fname1,dpi=200)
fig.savefig(fname2)

There's information about changing the math font here:

http://matplotlib.sourceforge.net/users/mathtext.html#fonts

You may be able to use "Symbol" as a custom font, but this is untested, 
as far as I know.  It would have to contain a Unicode mapping to be usable.

Hi all,

To annotate my figures with Greek letters, I use the following:

import matplotlib
matplotlib.use('PDF')
import matplotlib.pyplot as plt
from matplotlib import rc
rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})
plt.rcParams['ps.useafm'] = True
rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})
plt.rcParams['pdf.fonttype'] = 42
# plot figure
# ...
# annotate figure
plt.xlabel(r'$\mu$ = 50')
plt.ylabel(r'$\sigma$ = 1.5')

This makes the equal symbol and everything to the right of it in the
Helvetica font, as intended, and the Greek symbols default to the
usual TeX font (which I believe is Times New Roman.)

How can I make it so the font used for the Greek letters is the
"Symbol" font instead?  It's important for me not to have it appear in
the default Times font of TeX.

thanks for your help.

Hi all,
Thanks for the help so far.  One more question -
How do I completely remove the axes?
I currently have a plot where a square hatching of lines is deformed to 
create a sky projection, so the square block of axes actually gets in 
the way.  How do I remove it?

Cheers
Michael

Anyone have any suggestions?
