Cursor Class

Definition

Represents a horizontal or vertical line that defines a position along an axis.

public class Cursor : IDisposable
Inheritance
Cursor
Implements

Remarks

A cursor is a horizontal or vertical line that defines a position along an axis. A range selection is a range along an axis that is defined by a beginning and end position, and is displayed using a semi-transparent color.

Cursors and range selections are both implemented by the Cursor class, which is exposed as the CursorX and CursorY properties of the ChartArea object. The CursorX object is for the X axis of a chart area, and the CursorY object is for the Y axis. The AxisType property of these objects determines whether the associated axis is primary or secondary.

The only cursor and range selection functionality found outside the Cursor class are the events related to the cursor and range selection that are in the root Chart object.
