I would like to have values from my dataframe which I use to build my stacked bar chart displayed in the hovertool.
This issues came up already several times, but I haven’t found an easy solution.
So far I can access the Glyph Renderer from my bar chart likes this:
glyph_renderers = bar.select(dict(type=GlyphRenderer))
bar_source = glyph_renderers[i].data_source
And I thought about adding my values to the glyph renderes data source but I can’t really find the pattern of the glyph renderers.
