Because my interface is divided into several areas, each with different tasks, such as displaying videos or other data; But when I use PlotView to display real-time line charts, every time I call PlotModel InvalidatePlot(true); PlotView will flash the entire chat control screen, with a call frequency of 100 milliseconds each time. The cached points are 500, and if exceeded, the first point will be deleted; I have not seen any similar issues or solutions in the official documentation or demo; Therefore, this question is raised in the hope of obtaining a solution
