Using HoverTool formatters (datetime)

Hello,

I want to use the datetime formatting for the hovertool, but I'm not sure how to get it working.

So far I am adding and formatting my hovertool like this:

#add hovertool
tooltips = [
          ('Time', '@height')
       ]
hover = bar.select(dict(type=HoverTool))
hover.formatters = {'Time': "datetime"}
hover.tooltips = tooltips

My y-axis is in datetime format. But the Hovertool still shows my time as the full numerical value.

Cheers!

Hi,

The formatters dict should reference the CDS column name that you want to format, not the arbitrary tooltip label text:

    tooltips = [('Time', '@height')]

    hover = bar.select(dict(type=HoverTool))

    hover.formatters = {'height': "datetime"} # need CDS column name as key

Thanks,

Bryan
