Complete UI Freeze When mouse hover on chart lines or Axes

Post by abdul.qadirdeveloper » Tue Feb 14, 2017 11:33 am

I am using "LightningChart Ultimate WPF V 5" in my Existing WPF Applicaiton. I noticed that when we render chart with very large data, hover mouse over line chart or Axes lines or Axes title, Complete UI freezes including Chart.
I need to know why UI is freezing and how to fix it?
Is this a known issue with "LightningChart Ultimate WPF V 5"?

Hello,

LC v.5 is not maintained or supported anymore.

The mouse hit test is probably taking time. Set series.MouseInteraction = false to disable it.

LC v.7 has faster mouse-hit testing than v.5.
