SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, and iOS Chart & Android Chart Components
I followed the instructions in the tutorial “Custom ChartModifiers – Part 5 – Select and Drag a Data-Point” to create my program.
After moving data points by dragging using the mouse, I called IDataSeries.InvalidateParentSurface to redraw the chart. However, it doesn’t work. I also tried calling SciChartSurfaceBase.InvalidateElement() but doesn’t work either. The user needs to resize the Window in x-direction to redraw the chart. Is there anything I can do to make IDataSeries.InvalidateParentSurface working? Thanks.
