Data Editing in Blazor Charts Component

10 Aug 20233 minutes to read

Data editing allows the rendered points to be dragged and dropped at run-time. End user can adjust the points position or value based on its y-value. To enable data editing, set the Enable property in the ChartDataEditSettings to true. One can also use the Fill property to specify the color, and the MinY and MaxY properties to determine data editing’s minimum and maximum range.
