Faster Zoom

Post by ADJS » Wed Feb 05, 2020 1:23 pm

Is it possible to make the zoom operate faster? If you have many lines and/or much data in the lines the zoom operation is really slow, and it has problems drawing the zoom rectangle.

Hello,

There is no single property that will speed that up. It may be worth paying attention to factors of the Chart setup, ie. if any part of the chart has extra processing code on repaint that might be slowing down the paint cycle.
