Hover Scatter Plot Tooltip Behavior for Overlapping Points in Bokeh 0.8.0

Community Support
mitchjunk
mitchjunk

I am upgrading some embedded plots to Bokeh 0.8.0 to take advantage of some of the new features. I have noticed that the hover tool tip behavior has changed for scatter plots. My scatter plot is relatively dense in certain regions and when the hover tool hovers over these regions a long tool tip is displayed that essentially merges tool tips for any point that overlaps that region. In the previous build of Bokeh (0.6.0?) only one tool tip was displayed (probably for the most central point). That behavior is preferred over the much messier looking long list of tool tips I am getting now in 0.8.0. Is there an option to control this or different way of plotting (ex:circle plot) that will change the behavior back to only showing one tool tip? Thanks.

Hi Mitch,

There is currently no way to control the behavior when there are multiple hits in dens regions. There is an open issue for Hover tool improvements, and this in particular is one thing that is planned to be addressed. Basically there should be a policy to rate-limit the total number of hover tooltips rendered at any one moment, and also to put each hit in its own separate (dodged) tooltip. I am hoping this can go in 0.8.2 sometime in March.

Thanks,

Bryan

Hate to open an old topic, but was wondering whether this feature has been implemented or it has an open issue. Can’t find anything about rate_limit in the docs.

Not yet, I have a pretty clear notion of what needs to be done, but have not had any time to dig into it. If anyone else would like to take a crack at, I would love to describe the design I have in mind as well as help however I can with questions, etc.

Hi, it would be great to have some help on this front. There is currently some discussion and re-arranging going on around selections. It might be best to wait until the dust settles on that. Here are some discussions you might want to check into though, for now:

  Fix linked selections, unify select tools and remove selection manager model by canavandl · Pull Request #5158 · bokeh/bokeh · GitHub
  Improve Selection Manager · Issue #2328 · bokeh/bokeh · GitHub

Thanks,

Bryan
