Hi at all,
I have a numpy matrix (an image) and I'd like to show it.
I thought to use show function, but I have a question.
I don't want that the pixel have dimension 1x1 unit but I want for example 1X1.5 unit (I don't want a square but a rectangle).
How can I do this?
Thanks in advance.
Paolo
Hello,
check the help ;). you can set aspect='auto' or something fixed.
Regards,
Sebastian

Thanks for the reply.
I checked in the help...I didn't understand what I must to use.
Should you post me the link of the guide of this setting?
Thanks!

The solution is already the aspect='auto', ie:
import numpy as np
from matplotlib import pyplot as plt
a = np.arange(100).reshape(10,10)
plt.imshow(a, aspect='auto')
aspect='auto' is what you were looking for, the documentation (as you
probably already found is for example at:
http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.imshow
or in interactive help.

Actually, I think he’s wanting a set aspect, right? Either way, it’s just “aspect=1.5” or “aspect=0.6667” depending on the orientation he wants.

I have resolved using the aspect setting.
I calculated the ratio between the two pixel dimensions and I use
this value for aspect (if you want to shift the pixel size you can
use the inverse of this value).
Thank you for the support!
