Does anyone have a solution to the following issue (at least in LV8.5). When a chart contains about 400k datapoints programmatically changing the cursor becomes very slow (100msec). Even on a quad-core 2GHz machine (all in UI-thread?).
The attached file is an example of the issue. I would like to synchronise cursors in multiple graphs. Moving the cursor using the mouse gives response times <<1msec. When you clear the chart (remove data) the speed by setting is also normal.
Defer panel updates or disabling the graph doesn't change a thing. I did not see this item on the bug-fix list of 8.5.1. It seems that the whole graph is redrawn or something...
Kind regards,
Mark Beuvink
