  planesIntersectionCoordZ

Z-Coordinate of the planes intersection point.

  valueAxesType

Type of axes. You may use additional and percent axes only if you provide ticks for category axes. For example, if you are about to display additional columns, you should provide ticks for the X and Z axes. If you are about to display additional bars, you should provide ticks for Y and Z axes respectively (because bars are stretched along the X-axis). If you didn’t provide ticks for category axes, changing the type to additional or percent takes no effect for the series displayed even though states of their points are aligned to the grid (see NChartPointState for details).

  borderColor

– addCrosshair:

Add crosshair to the cartesian system.

- (void)addCrosshair:(NChartCrosshair *)crosshair

Parameters

crosshair
  • crosshair to add.

See Also

Declared In

NChartCartesianSystem.h

– removeCrosshair:

Remove crosshair from the cartesian system.

- (void)removeCrosshair:(NChartCrosshair *)crosshair

Parameters

crosshair
  • crosshair to remove.

See Also

Declared In

NChartCartesianSystem.h

– removeAllCrosshairs

Remove all crosshairs from the cartesian system.

- (void)removeAllCrosshairs

Declared In

NChartCartesianSystem.h

– updateCrosshairs

Force crosshairs to be updated.
Use this method if you changed values of crosshairs and want to apply them without calling updateData of the chart. If crosshairs are the only changed chart items, this is much more efficient way to make the changes visible than updating entire chart.

- (void)updateCrosshairs

Declared In

NChartCartesianSystem.h

– addPlane:

Add plane to the cartesian system.

- (void)addPlane:(NChartPlane *)plane

Parameters

plane
  • plane to add.

See Also

Declared In

NChartCartesianSystem.h

– removePlane:

Remove plane from the cartesian system.

- (void)removePlane:(NChartPlane *)plane

Parameters

plane
  • plane to remove.

– removeAllPlanes

Remove all planes from the cartesian system

  shouldAutoZoom

Flag determining if auto zoom mode is on (YES), or off (NO). The default value is NO.
In auto zoom mode, the axis set to be auto-zoomed by the autoZoomAxes property is zoomed automatically so that the visible part of the chart is fit to the plot area.

@property (nonatomic, assign) BOOL shouldAutoZoom

Discussion

This property takes effect in 2D mode only.

Declared In

NChartCartesianSystem.h

  autoZoomAxes

The axes kind (normal, secondary or both) to be auto-zoomed. The default value is NChartAutoZoomNormalAxis.
The axes set to be auto-zoomed are zoomed by panning so that the visible part of the chart is fit to the plot area, if shouldAutoZoom is YES. If axes are not swapped (you are not using bar series), the axes to zoom are Y and SY. In other case, they are X and SX.

@property (nonatomic, assign) NChartAutoZoomAxes autoZoomAxes

Discussion

This property takes effect in 2D mode only.

It is strongly recommended to disable the user interactions related to the direction of the axes which should be zoomed automatically. For example, if you set autoZoomAxes to NChartAutoZoomNormalAxis, and the axis are not swapped (you are not using bar series, so the axes to zoom are Y and SY), you are recommended to disable proportional zoom, vertical zoom and vertical pan: m_view.chart.userInteractions = (m_view.chart.userInteractionMode) ^ (NChartUserInteractionProportionalZoom | NChartUserInteractionVerticalZoom | NChartUserInteractionVerticalMove);, as well as to set the zoomMode to directional: m_view.chart.zoomMode = NChartZoomModeDirectional;
