The script run_all.py in the basemap examples does not work when Python has
been installed to "C:\Program Files\Python25". It appears that this problem
involves the space in the path.

I believe the OP was asking how to position the entire figure Window (or 
frame in wx parlance) on the screen, rather than the axis within the figure.
If you are using the wx back-end, you should be able to get a reference 
to the wx.Frame, and do what you like with it. (sorry, I don't remember 
how to do that off the top of my head, though if need be a few calls to 
GetParent should get you there).
If you are using another back-end there should be a similar calls available.
However, given your description, I suspect that you'd be better off 
managing the frames with your code anyway. Take a look at wxMPL 
(http://agni.phys.iit.edu/~kmcivor/wxmpl/) and/or the "embedded_in_wx" 
examples.

Hi marie,
You can define exactly the size and position of your plot like this:
fig = Figure()
axe = fig.add_axes([pos_x,pos_y,size_x,size_y])
axe.plot(x, y, 'b')
where pos_x,pos_y is a number (0<n<1) and 0,0 is bottom left
size_x, size_x is a number (0<n<1)
1 is full figure size.
Ex: axe = fig.add_axes([0.1,0.1,0.8,0.2])
Plot @10% x,10% y from bottom left
And size is 80% of figure x size and 20% of figure y size.

Objet : [Matplotlib-users] set figure position
We have recently switched to matplotlib after having done all plotting with
pure wxPython for years.
There is one problem we cannot solve. With wxPython we are free to set the
geometry (position and size) of each Frame anywhere on the screen. We have
developed a heuristic solution which packs the Frames automatically
according to a pattern that can be recognized after a user has manually
repositioned a few Frames on the screen. For example, some users tend to
align their figures in a row, others subdivide the available space for
different groups of figures, and so on. Please let us know if anyone is
interested to integrate this heuristic packing into matplotlib.
The important question is:
How can we set the position of a Figure on the screen using matplotlib?
There is a function Figure.set_size_inches, but no function to move the
Figure to a new position. Please help.
Regards,
Marie

Hi,
RTFM...indeed it works.
However, the axis do not scale accordingly:
quiver([1],[1],[2],[2], angles='xy', scale_units='xy', scale=1) on a 
TkAgg backend produce a plot with:
In [11]: axis()
Out[11]:
(0.94000000000000006,
 1.0600000000000001,
 0.94000000000000006,
 1.0600000000000001)
The display area scales the same way as it does using 
quiver([1],[1],[2],[2]) (without any other args).
It looks like a bug.

Hi Xavier,
You can pass some handy keyword arguments to fix that. Use the following:
quiver([1],[1],[1.2],[1.2], angles='xy', scale_units='xy', scale=1)
Hope that helps :)

We have recently switched to matplotlib after having done all plotting with pure wxPython for years.
There is one problem we cannot solve. With wxPython we are free to set the geometry (position and size) of each Frame anywhere on the screen. We have developed a heuristic solution which packs the Frames automatically according to a pattern that can be recognized after a user has manually repositioned a few Frames on the screen. For example, some users tend to align their figures in a row, others subdivide the available space for different groups of figures, and so on. Please let us know if anyone is interested to integrate this heuristic packing into matplotlib.
The important question is:
How can we set the position of a Figure on the screen using matplotlib? There is a function Figure.set_size_inches, but no function to move the Figure to a new position. Please help.

Hi,
I woud like to draw a vector field using pylab.
quivert looks nice but it sould not scale the arrows to fit my use-case.
quiver([1],[1],[1.2],[1.2]) does plot a nice arrow but the head of the 
arrow is not at (1.2,1.2).
Is there a way to plot a list of arrows *without* any scaling?
Xavier

Hi Jae-Joon and others,
i switched to using splines, but i still cannot see how to adjust the
space between the axis labels and the ticks of the axes. right now the
labels are too far away.
here is my code:
fig = plt.figure()
x = np.linspace(0,2*np.pi,100)
y = 2*np.sin(x)
ax = fig.add_subplot(2,2,1)
ax.plot(x,y)
show_spines(ax,['left', 'bottom'])
plt.xlabel('xlabel')
plt.ylabel('ylabel')
ax = fig.add_subplot(2,2,2)
ax.plot(x,y)
show_spines(ax,['left', 'bottom'])
plt.xlabel('xlabel')
plt.ylabel('ylabel')
ax = fig.add_subplot(2,2,3)
ax.plot(x,y)
show_spines(ax,['left','bottom'])
plt.xlabel('xlabel')
plt.ylabel('ylabel')
ax = fig.add_subplot(2,2,4)
ax.plot(x,y)
show_spines(ax,['left', 'bottom'])
plt.xlabel('xlabel')
plt.ylabel('ylabel')
plt.savefig('test.pdf')
i don't see how i could switch to plt.text or plt.annotate here. the
xlabel and ylabel functions automatically plot the label of an axis in
the center, which is exactly what i need. computing where the
coordinates where a label should be plotted with plt.text so that the
label appears in the center seems very messy and difficult, since it
requires knowing how much space the label will take (and that depends
on the font size etc.)
is there an existing parameter that just controls the distance between
the xticks and the label? it seems like there must be.. i just want to
bring them closer together.
thank you.

I was trying to build matplotlib 0.99.0 as part of Sage
http://www.sagemath.org/
on a Sun Blade 2000 workstation running Solaris 10 update 7, using the Sun 
Studio compiler version 12.1 (not gcc).
CC and CXX were defined properly as C and C++ compilers, but it would appear 
that the C compiler is being called to compile the file src/ft2font.cpp, which 
is of course a C++ file.
You might get away with this with gcc, but the Sun C compiler will not compile 
C++ code.
Here's the error I get:
/opt/xxxsunstudio12.1/bin/cc -DNDEBUG -O -xcode=pic32
