show scaled image (matlab imagesc)

Hello,

Is it possible to autoscale the color map of an image (as in matlab’s ‘imagesc’)?

I’m using imshow and I can use vmin and vmax but than I have to set these values manually.

Thanks,

Sahar

If you don’t give it a range, it should autoscale by itself. Double check to make sure there isn’t a spurious value somewhere in your array. Otherwise, we’d need to see a complete, small example that demonstrates the problem you’re seeing, as well as your version of matplotlib.
