“several hundreds” should not be a problem at all

TGraph2D Drawing Very Slow

Hi, I’ve got a TGraph2D with 1000 data points, which doesn’t seem excessive to me, but Drawing the object takes a very long time, even with the default drawing options. Is 1000 points too much to draw the graph reasonably quickly? Are there some drawing options that could be recommended for large graphs? My graph can be recreated by doing “.x graph2d.C” using the attached macro, then you can draw it using whatever option you wish for testing. The points are in a regular grid. Is there a bet…

TGraph2D Delaunay interpolation holes

[image] There are some holes when I draw a TGraph2D. There is an example in the attached root file. You can reproduce the problem by doing: graph2Dexp68->Draw(“P”) graph2Dexp68->Draw() You can see the holes along the x = y axis. output_file.root (6.88 KB)
