NChartCartesianSystem.h
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).
@property (nonatomic, assign) NChartValueAxesType valueAxesTypeSee Also

NChartCartesianSystem.h
borderVisible
Flag that determines if the border around the cartesian coordinate system is visible (YES) or not (NO).
@property (nonatomic, assign) BOOL borderVisibleDeclared In
NChartCartesianSystem.h
borderColor
Color of the border around the cartesian coordinate system.
@property (nonatomic, strong) UIColor *borderColorDeclared In
NChartCartesianSystem.h
borderThickness
Thickness of the border around the cartesian coordinate system.
@property (nonatomic, assign) float borderThicknessDeclared In

– addCrosshair:
Add crosshair to the cartesian system.
- (void)addCrosshair:(NChartCrosshair *)crosshairParameters

– removeCrosshair:
Remove crosshair from the cartesian system.
- (void)removeCrosshair:(NChartCrosshair *)crosshairParameters

NChartCartesianSystem.h
– removeAllCrosshairs
Remove all crosshairs from the cartesian system.
- (void)removeAllCrosshairsDeclared 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)updateCrosshairsDeclared In
NChartCartesianSystem.h
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 shouldAutoZoomDiscussion
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 autoZoomAxesDiscussion
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;
