Hi Prasad,

Thank you for using the Syncfusion products.

We have analysed the reported requirement. You can able to achieve the editing data plot in SfChart by help of dragging support. We have a dashboard sample for this. Please find the dash board sample location in your system.

Code snippet [XAML]:

<chart:LineSeries Label="Sports" ItemsSource="{Binding CategoricalDatas}"

                    XBindingPath="Category" YBindingPath="Value" UpdateSource=”True’

                    EnableSegmentDragging="True"/>

This feature allows us to drag the data points along y-axis. The following series types support this feature: (Line, Column, Bar, Spline, RangeColumn)

The following events are used to interact with dragging:

Event Name	Description
DragStart	Occurs when series or segment receives logical focus and is selected by the mouse.
DragDelta	Occurs one or more times as the input device changes position when a series or segment has logical focus and is selected by the mouse.
DragEnd	Occurs when series or segment is no longer selected by the mouse.
SegmentEnter	Occurs when the input device enters the segment.
