Scatterplot: click on legend should filter out points

[dvdanielamoitzi]

Short description

When I click on a legend item in the Scatterplot, the category should be filtered out of the plot.

Maybe switch to the new legend right away, instead of using a plotly legend?

I just discovered, filtering by interacting with the legend no longer works, neither in the hexbin plot nor in the new scatter plot implementation
