Data editing in Angular Chart component
27 Apr 20247 minutes to read
Enable Data Editing
We can use the data editing through inject the DataEditingService
module. It provides drag and drop support to the rendered points. Now, we can change the location or value of the point based on its y
value. To enable the data editing, set the enable
property to true in the drag settings of the series. Also, we can set color using fill
property and set the data editing minimum and maximum range using minY
and maxY
properties.
