Hi,
I want to make a figure that has three subplots. The top one should
be a big, mostly square thing. The bottom two should be rectangular
things. That is, I want it to look like this:
XXXXX
XXXXX
XXXXX
so, I'm using subplot(311), subplot(312), subplot(313). But, things
are getting resized so that each of the rows has the same height.
That really messes up the aspect ratio for my top row.
I tried axis('equal') and axis('scaled') after making the first
subplot. I do indeed get a good aspect ratio, but it shrinks things
to do this, rather than stretching things. I'd really like the top
row to be taller than the bottom rows. How can I do this?
If it matters, I make the top box with pcolormesh and the bottom
rectangles with plot.
Thank you,
-michael

Hi,
Sorry if I'm just being thick .. I read through several of the
examples, and didn't figure it out. I can figure out how to use
figsize to set the size of the entire figure, but I want several
subplots on one figure. Maybe you can help me fix some sample code.
This plots a matrix and sqrt(x)/2. I'd like to have the matrix show
up as a square while sqrt(x)/2 shows up as a rectangle. The call to
axis('scaled') makes my matrix show up as square, but I'd like it to
be stretched out so that it uses up all of the horizontal space and
makes the figure taller. That is, I want row 1 to be taller than row
2.
Thanks,
-Michael
#!/usr/bin/env python
from pylab import *
subplot(211)
mat = array([[1,2,3],[4,5,6],[7,8,9]])
pcolormesh(mat)
axis('scaled')
subplot(212)
dt = 0.001
t = arange(0.0, 10.0, dt)
root_t_over_2 = (t/2.0)**0.5
plot(t,root_t_over_2)
show()

See the examples.
You just have to set figure size you need.
f = Figure(figsize=(5,4), dpi=100)

The following might hrlp:
ax1 = subplot(211)
ax2 = subplot(413)
ax3 = subplot(414)

And if you want to tweak the positions you can use, e.g., oldpos = ax1.get_position() to find out the present position, and ax1.set_position(newpos) to change it. The position rectangles are [left, bottom, width, height] in relative coordinates--that is, fractions of the figure width and height.
If you want to control the aspect ratio of the data without changing the position rectangle (e.g. after adjusting it as above), use
ax1.set_aspect(aspect, adjustable='datalim').

I recently attended a fantastic workshop by John Hunter and Fernando
Perez, and John pointed out that I really do want to play with the
axis objects directly. In case someone googles for this later on,
here's how to do it for two boxes:
ax = axes([0.1, 0.3, 0.8, 0.6])
plot(rand(12))
a2 = axes([0.1, 0.1, 0.8, 0.15])
plot(rand(12))
