Annotating bokeh chart plot
It's always possible to use .add_glyph directly, but it is a bit of a pain. The feature to add all the "glyph methods" e.g. .circle, .rect, etc. is in GitHub master, and will be available in the upcoming 0.12 release.
Is it possible to annotate or add markers of any form to Bokeh charts (specifically Bar graphs)? Say I want to add an * (asterisks) on top of a bar; is this possible?
