Way to get log axes with datashader dsshow and matplotlib

[rotheconrad]

Is your feature request related to a problem? Please describe.

I cannot find a way to get dsshow to return the points with a log axis or convert them to a log axis with matplotlib.

Describe the solution you'd like

Better documentation with instructions or feature addition if it is not currently doable.

Describe alternatives you've considered

dsshow doesn't appear to be fully linked to other datashader functionality. Matplotlib controls do not work to manipulate the object returned by dsshow.

Additional context

I believe this doesn't depend on versions or any other context.

Good point. Setting it up on the Datashader side should just require passing x_axis_type='log' and/or y_axis_type='log'when creating the Canvas in datashader.mpl_ext.DSArtist.aggregate. I don't know what's required on the Matplotlib side, though. @nvictus or @tacaswell ?

Matplotlib controls do not work to manipulate the object returned by dsshow.

Can you be more specific and provide examples? I'm not sure what's missing here.
