Sure, for now you just have to do it manually. My proposal above is for us to do most of the work for you, and to do it using the aggregated data so that it's super-fast, but you can always add selection tools and compute ranges "by hand". There's an example at https://github.com/pyviz-demos/glaciers , which can be run live on binder: https://mybinder.org/v2/gh/panel-demos/glaciers/master?urlpath=/proxy/5006/app

I found this while searching for some sort of select tool to use with Datashader.
I can subsample the data just fine and use in Bokeh or Holoviews with Bokeh on the backend but when using my full dataset neither can display the plots without slowing down the PC extremely. When I display with Datashader the selection tools don't work.
Is there a recommended work around for displaying datasets > 1M points with selection capabilities?

Thank you

I think the recent link_selections
support in HoloViews addresses some of this need, but it's still a relevant feature request: draw a box or lasso, then show via hover the aggregated values in that region.
