Extract subset of data from scatter plot

I have a scatter plot of 1000+ data points.
I'm looking for options to extract a small subset
of data points that cluster together on the plot. While the hover tool lets us look at individual data points, is there a way to select an area on the plot and extract all data points within it?

Thank you!!

Hi,

There's nothing build into Bokeh to do this, but you could potentially create a tool yourself in a couple of different ways:

* with callbacks on the new UI events:

  http://bokeh.pydata.org/en/latest/docs/reference/events.html
  https://github.com/bokeh/bokeh/blob/master/examples/howto/js_events.py
  https://github.com/bokeh/bokeh/blob/master/examples/howto/events_app.py

* by creating a custom extension:

Thanks,

Bryan
