Hello,
I have a line chart consisted of series of ~4K points each. The performance problem appears even with only one series (so 4K points total) which has the following point distribution:

Here I explain the problem.. I want to zoom in, so I'm selecting chart areas. Before actually selecting the area, we get a highlighted rectangle until the mouse button is released. When the highlighted area contains plot segments, or even when it's close to plot segments, the program starts slowing down.
From what I understand, the above happens because sequential (in respect to xAxis) points have big differences in their y-values, so the lines that join points are longer. When I am drawing ~4K points that lie on a straight line, there is no performance drop at all.
What is the technical limitation that produces this kind of behaviour? Can I fix it somehow?
Thanks
