Changing selection using js

Hello,

I have a Bokeh scatter plot (embedded in a web app) in which I’d like to be able to highlight particular data indices.

I know that I can get the current selection indices using:

Bokeh.ColumnDataSource.Collection.models[0].attributes.selected

But is there a setter that I can use to update these indices, so that the corresponding points are highlighted?

Thanks for your help,

Stephen

These are backbone models, you should be able to update the selected indices with something like:

  source.set('selected', [10, 27, 52])

It's possible that merely setting the selection won't trigger a re-render request (I can't recall offhand). To make sure a re-render happens, you can also trigger the 'change' event on the source:

  source.trigger('change')

Thanks,

Bryan
