Detailed Description

The NChartCrosshair class provides methods to control crosshairs - lines that are perpendicular to the axes and are to mark some position on the chart.

Single chart can have multiple crosshairs either connected to the chart points or free (with user defined coordinates).

Constructor & Destructor Documentation

com.nchart3d.NChart.NChartCrosshair.NChartCrosshair ( int  color, float  thickness, NChartPoint  targetPoint  )

inline

Create crosshair with color, thickness and target point.

Parameters

color	- color of the crosshair.
thickness	- thickness of the crosshair.
targetPoint	- tracking point of the crosshair.

Member Function Documentation

NChartCrosshairDelegate com.nchart3d.NChart.NChartCrosshair.getDelegate ( )

inline

Crosshair delegate.

For details see NChartCrosshairDelegate

Bitmap com.nchart3d.NChart.NChartCrosshair.getImage ( )

inline

Image that is displaying in the crosshair.

The default value is null.

PointF com.nchart3d.NChart.NChartCrosshair.getImageOffset ( )

inline

Offset in pixels of the image from the crosshair's center.

The default value is (0,0).

NChartPoint com.nchart3d.NChart.NChartCrosshair.getTargetPoint ( )

inline

Target point for the crosshair.

Use this property to set crosshair to track chart point.

float com.nchart3d.NChart.NChartCrosshair.getThickness ( )

inline

Thickness of the crosshair in pixels.

The default value is 1.

boolean com.nchart3d.NChart.NChartCrosshair.shouldJumpToTouch ( )

inline

Flag determining if the crosshair should move to the touch wherever the touch location is.

The default value is false. If this flag is true, all the touches are catched by the topmost crosshair (the one that was last added to the cartesian system of the chart). So no other user interactions like pan and point selection are possible in the chart.
