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?
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.
