Hover over tick labels

Community Support

Hi,

I’m trying to have a hover effect on the tick labels of one axis. I’m using BokehJS.

I know that’s a fairly esoteric thing to do. So far I have failed to find a rendered in the object graph that I could pass to HoverTool.

Any pointers for this weird quest are welcome, thank you.

All right that’s fair.

Knowing essentially nothing about how Bokeh actually renders: Are the labels in the end DOM objects (or similar), and is there away to find them after the plot has rendered to manipulate their events?

With a few exceptions, like the hover tool itself, Bokeh renders plot objects as pixels to HTML or WebGL canvas, so there are no corresponding DOM elements to, e.g. a Bokeh axis or tick label.
