selection_glyph is not defined when adding glyphs to figures

Hi,

I’m trying to change the appearance of a patch when it’s selected with the TapTool. I’m creating a figure and adding some patches like:

p = figure(some_args)

p.patches(‘xs’,‘ys’, source=source, name=“my patches”)

glyph = p.select(name=“mypatches”)[0].selection_glyph

glyph.line_color = “blue”

But the glyph that it’s returned is NoneType. Checking the code inside _glyph_function it seems that only the glyph and nonselection_glyph member variables of the GlyphRenderer are initialized.

I just started using Bokeh, is this the correct way if editing the appearance of glyphs for tap events? Thanks a lot for your help and for creating such a great library!

Best,

Alonso

I’m not so great with the plotting interface, but I can tell you how to do this using the low-level interface in case that’s any help.

Hi Sarah,

Thanks a lot for the quick reply! I actually saw your awesome talk on Youtube and I’ve been looking through that code. I’m having some troubles passing the adequate parameters to Plot (it doesn’t display my map at all, maybe I’m setting the x and y ranges incorrectly), that’s why I was using figure() instead.

Best,
