Typically, images in matplotlib are associated with "da
If you're just looking for the dimensions of the overall figure in pixels,
you can easily access them through other means. E.g:
import matplotlib.pyplot as plt
fig = plt.figure()
_, _, width, height = fig.bbox.extents # <- Extent of the figure in pixels
fig.savefig('temp.png', dpi=fig.dpi) # <- Be

This is interesting. It seems that the event.x, event.y values are for
the entire figure area rather than limited to the image. Anyone know
how to get the image values instead?
Also, I wonder how one might get the values of the pixels (i.e. image
value) at the pixels that you click on. One more

Why do you say it's wrong? Note that in mpl, (0,0) is (bottom left),
not (upper,left). So this is saying that the yellow dot at 10,20
(data coords) is 576 pixels up from the bo
Hi John,
thanks for the reply, but I think your method is not working:

Hi,
I would like to know how to find out the extend of the actual image in a
plot, in units of pixels.
As example I have attached a plot which is essentially empty. The lower left
corner is indicated by a red dot - what pixel position does this location
have? When opening this image in e.g. kview
10 matches
