[bokeh] Categorical heat maps / groups

Hi,

The best way to help others help you is to provide actual sample code. It's usually difficult/impossible to offer specific advice without seeing or ideally running real code. Offhand the only thing that comes to mind is that if you are really ordering things (year, decade) then that would seem to be ordering the groups/subgroups backwards.

E.g. compare to

Thanks,

Bryan

Hi everyone. Is there a way to do the heat maps example posted here: https://bokeh.pydata.org/en/latest/docs/user_guide/categorical.html#heat-maps but grouping together decades?

That is, with the x-axis showing 80's, 90's, 00's, 10's etc. instead of each individual year? I've been trying to use the same principles as described in a different example where I set up FactorRange(*x), with x being [(year, decade), ...] but no luck so far.
