How to deal with large dataset

[sim186]

Hi,

I'm here again. I noticed that swiching from a scattered plot to a line plot increase a lot the computation time during the "setGraphVisibile" call.

My question is: I'm using it in the right way or is expected to have such a different during the rendering? (I mean in principle I expect that a scatter is easier to draw than a line chart).
