Enhancements to imshow

[hansenms]

We should add:

• Colorbar
• Some way of looking at pixels

[inati]

What do you mean by looking at pixels? Do you mean clicking on a point to get its value?

[hansenms]

@inati, yes, something like that. Ability to plot a like would be great too and drawing a circle or something.

[hansenms]

I added an option to get a colorbar.

[naegelejd]

I wrote a simple event handler for click events and I can print the value
of the selected point to the terminal, but I'm not sure how useful that is.
Would you rather it pop up in a message box, appear dynamically in the
original plot window, or something else?

I will take a look at what you did, but I think we should probably sit down and discuss what functionality we would like and how hard it is to do.

here are a couple resources of possible interest:

For interactive 2D plotting and the ability to draw lines for plotting line profiles, etc. there is some nice code in the viewer module of scikit.image. specific example:
https://github.com/scikit-image/scikit-image/blob/master/viewer_examples/plugins/lineprofile.py
The viewer displays coordinates and corresponding pixels values as well.

There is also a pretty good interactive orthogonal slice viewer for 3D/4D volumes proposed in this PR for nibabel:
