Can I interactively review points that belong to specific plots in multiple scatterplots and other multiple graphs?

Identifying all points of a plot. In the (default) pointing mode (when the point tool is enabled), click on any point that belongs to the specific plot and all points of that plot will become highlighted. They will stay highlighted for as long as you keep pressing the mouse button. If there are many plots in the graph, and their respective point markers are small and difficult to identify, then you can click on the legend. This will also highlight all points that belong to the respective plot.

Identifying individual points of a plot
If you need to identify values of specific points in the graph, use the Brushing Tool .
