It would be nice to add an
alphaproperty to the plotter that controls, well, the alpha-value of drawn points. Its usage would have to be restricted to the scatter artist as there wouldn't be any real equivalent for a 2D histogram.In the scope of the clusters plotter, this parameter could then help to move out-of-timeframe points/objects into the background of the plot.
