Winform Chart BorderDashStyle set to Dash, programe freeze

Jane Pan 0

We use Chart Control to plot the curve. When BorderDashStyle set to Dash, the response of the software interface and switch interfaces is very slow. Such as when switching from another interface to this interface with chart control, the area of chart's shows more stuttering than the others. But when BorderDashStyle set to Solid, the situation has improved considerably. The same goes for BorderDashStyle set to DashDot, DashDotDot, Dot, the response of the software is very very slow. Does the setting of the lineform affect the rendering speed? Where can I get offical instructions about similar question? Thanks a lot.

@Jane Pan Hello, I haven't found any documentation about the performance of BorderDashStyle for the time being, and I will let you know if I find it later. I run a simple Chart program. I used the performance monitoring in the task manager that comes with Windows. It is found that the CPU usage rate is 80% when running Dash, and the CPU usage rate is 83% when running Solid. Solid has higher performance requirements in my tests. Could you please provide your minimal reproducible example code?
