Would placing this in plot_tools.py be better? I assume its only the line-hover that will be using this?

[eilskra]

or in the tooltip_manager

[eilskra]

Should this be named rejected_scatter_data or something along those lines? When we remove Extended plot information we will plot the accepted as scatter points too
