Using Hover Tool

Hi all,

I have been exploring using the Hover Tool on plots within IPython, it looks pretty cool.

I have run into two problems:

1. The hover only works on scatter plots

2. If you have more than one scatter plot, you can only hover over points from the last plot.

I am doing something wrong or are these current limitations?

Thanks,

Zach Jones

Hi Zack,

Regarding 1), in addition to scatter markers, the hover tool also works with 'rect' glyphs as well. I hope to add support for annular and wedge shapes and lines of the upcoming 0.5. If you (or anyone else) is interested in getting your hands dirty, it's just a matter of implementing the _hit_point method on the relevant bokehjs renderer.

As for 2) that might be a bug, but it also might just be that you need to re-use the datasource (the render functions take a "source" keyword argument). Check out the periodic.py example in examples/plotting/file. If that does not work, please file a GitHub issue!

Zach,

In the just release 0.4.2, hover now works on more glyph types (annulus, annular_wedge, and wedge in addition to rect and circle and all the markers) and the bug preventing it from working on multiple renderers has also been fixed.

Thanks,

Bryan
