> I am trying to write a small bit of code that interactively deletes selected slices in an image series using matplotlib. I have created a button 'delete' which stores a number of indices to be deleted when the button 'update' is selected. However, I am currently unable to reset the range of my slider widget, i.e. removing the number of deleted slices from valmax. What is the pythonic solution to this problem?

If I've read your intentions correctly the line above should read

self.slider.valmax = len(self.raw_dicom_stack)

If I'm wrong then please ask on the matplotlib users mailing list or 
possibly stackoverflow.
