Updating vmin and vmax in imshow

Community matplotlib-users
#1

Hello,

I am plotting a numpy array with

image = imshow(array,vmin=0,vmax=100)

If I want to change the array, I can then do

image.set_data(new_array)

and I can also update the colormap, etc. But I can't find any options to update the vmin and vmax values. Am I missing something? What I am looking for is something like this:

image = imshow(array,vmin=0,vmax=100)
image.set_vmin = 10

but there is now such function.

Thanks,

Thomas

You will have to call draw() because the OO interface does not do so automatically. Or you can use the pyplot clim() function, which does call draw.

image.set_clim(vmin=10)

This works great - thanks!
