pseudo colour maps with colorbar

[ocehugo]

Bokeh supports pseudo-color plots with dynamic colorbars?

Example: Can I do a pseudo color plot ( or filled contour aka contourf) with bokeh and let the user adjust the colorbar limits to highlight some specific ranges ? A topography map is the most classical example that this would be very useful, using the adjustable colour range to explore several ranges of topo values in 2d.

Bokeh supports explicit RGBA image plots, or colormapped image plots based off 2d scalar data. We still need to add a color bar, I would expect this late April/early May release (probably soon in master on GitHub). An adjustable color bar for selections is also a fantastic tool, we are still working integrating widgets so I am not sure what the time frame for that would be, hopefully if not the release I mentioned above, then the one after.

Created feature issue #1441 to cover adding color bar feature, closing this discussion.
