Selection in React Chart component
19 Sep 202424 minutes to read
Chart provides selection support for the series and its data points on mouse click.
When Mouse is clicked on the data points, the corresponding series legend will also be selected.
We have different type of selection mode for selecting the data. They are,
- None
- Point
- Series
- Cluster
- DragXY
- DragX
- DragY
Point
You can select a point, by setting selectionMode
to point.

Rectangular selection
DragXY, DragX and DragY
To fetch the collection of data under a particular region, you have to set selectionMode
as DragXY
.
- DragXY - Allows us to select data with respect to horizontal and vertical axis.
- DragX - Allows us to select data with respect to horizontal axis.
- DragY - Allows us to select data with respect to vertical axis.
The selected data’s are returned as an array collection in the dragComplete
event.
