axis aspect ratio

Community matplotlib-users

Hello everyone,

I’m using matplotlib for plotting data results from numerical simulations that involve a lot of geometric calculations.

I did read the tutorial, but I haven’t been able to figure out the proper way to set the axis aspect ratio to “1” when

numerical data is plotted.

Here is an example of my plot:

since I need the aspect ratio to be “1” so that I can visually inspect my numerical code for bugs, I would really

appreciate the help.

I’ve loaded the data using pylab.load and I’ve plotted the files without using figure or axes, just plain old

pyplot.

Give this a shot:

import matplotlib.pyplot as plt

fig = pl.figure(figsize=(4,4))

ax = fig.add_sublot(1,1,1) # tweak as needed

[plot your data]

ax.set_aspect(‘equal’)
