Hi,
I am trying to update the image plotted in a figure. From what I understood, this code should do the job:
import pylab as p
image=p.zeros((20,20))
p.ion()
ax=p.imshow(image)
p.draw()
for i in range(10):
print i
p.ion()
image[i,:]=i
ax.set_array(image)
p.draw()
But the image is not updated at all…
what am I doing wrong?
I have the 0.99.1.1 version of matplotlib.
Cheers,
Chiara
set_array method only update the underlying array, and no more.
The problem is that, the first imshow results in clim=(0,0) and
set_array does not change this.
You may manually update the clim of the image, or you may explicitly
call autoscale() after set_array.
