I have recently started using the Donut chart capabilities in 0.12.4 and ‘hover_tool’ is one of the parameters that can be supplied when creating the chart. It is set to True by default.
However it doesn’t seem to add hover capabilities to the donut chart, at least for me. I have also tried to add a string to *hover_text *to see if that made a difference, but that doesn’t do anything either.
Is this a known bug, or am I just doing something stupid?
