Hover does now work for lines.
You would do add_glyph twice:
- for all your data that you don’t want to hover and
- for the line you do want to hover
add_glyph returns the renderer.
Then, when you make your hovertool, you specify the renderer. Something like this:
p = Plot(**plot_config)
line = Line(**line_config)
hover_on = p.add_glyph(hover_source, line)
hover_off = p.add_glyph(non_hover_source, line)
p.add_tools(HoverTool(tooltips=tooltips, renderers=[hover_on]))
You can see an example of specifying the renderers for tooltips in the examples folder here: https://github.com/bokeh/bokeh/blob/master/examples/glyphs/data_tables.py#L56

For example, I’d like to plot several lines, and enable tooltips for only one of them.
Currently, there doesn’t seem to be a way to do this easily. The only approach I could come up with is to draw other lines as images.
There is an answer on StackOverflow that suggests the same: http://stackoverflow.com/a/29465823/2175968
But this approach has obvious drawbacks.
Is there a better way to do this? Does new features need to be implemented to achieve this? If so, are there any plans?
