hi all,
i have a series of subplots organized in a column (3x1). i noticed that if i plot them then matplotlib tends to make the x-axis long and the y-axis short, so the plot is really rectangular. how can i make it more square? if i do:
f = figure(figsize=(7,6), dpi=100)
p1 = subplot(3,1,1)
plot(…)
make axes square
p1.set_aspect(‘equal’)
p2 = subplot(3,1,2)
plot(…)
p2.set_aspect(‘equal’)
etc for third subplot…
then the subplots i get are square, but very small and squished compared to the space they have in the figure (ie what i set in figsize.) how can i fix this? i just want to have square axes, but have each subplot take up as much space as it would if i didnt set square axes… it works fine for the rectangular axes case.

Maybe what you are looking for is
p1.set_aspect('equal', adjustable='datalim')
It is not clear from your message, but try the modification above and see if it does what you want.

hi eric,
i tried your suggestion but it still did not work. here’s a code snippet that demonstrates what i am trying to do:
import matplotlib.pyplot as plt
from scipy import *
my_fig = plt.figure(figsize=(7,6), dpi=100)
plot_ax1 = plt.subplot(3,1,1)
a = rand(100)
b = rand(100) + rand()
plt.scatter(a, b)
plot_ax1.set(xticklabels=)
plot_ax1.set_aspect(‘equal’, adjustable=‘box’)
plt.savefig(‘myplot.pdf’)
when i run this, i get a small square scatter plot in the middle of the page. i want this plot to be scaled to be bigger. if i remove the set_aspect() call, the plot becomes bigger in the horizontal direction, and is rectangular.
any ideas how to fix this? thanks again.

No, I'm still baffled. If you stack 3 subplots vertically in a figure 6 inches high, they are going to be small. You can fiddle with their sizes a bit by using subplots_adjust, but they are still going to be small--less than 2 inches high. What physical dimensions do you want, when you say you want the plot to be "scaled bigger"?
