  name

Name of the series.

@property (nonatomic, readonly) NSString *name

Declared In

NChartSeries.h

  nameColor

Color of the series name displayed in the legend. If nil, the textColor from the legend is used. The default value is nil.

@property (nonatomic, strong) UIColor *nameColor

Declared In

  disabledNameColor

Color of the series name displayed in the legend when the series is hidden (aka disabled). If nil, the textColor from the legend is used. The default value is nil.

@property (nonatomic, strong) UIColor *disabledNameColor

Declared In

  image

Image that is displayed in the legend. This property returns the image only if it was provided by the data source. If the default image is used, nil is returned.

@property (nonatomic, readonly) UIImage *image

Declared In

  disabledImage

Image that is displayed in the legend when the series is hidden (aka disabled). This property returns the image only if it was provided by the data source. If the default image is used, nil is returned.

@property (nonatomic, readonly) UIImage *disabledImage

  legendMarkerSize

Size of default series' marker in legend in pixels. The default value is 20.

@property (nonatomic, assign) float legendMarkerSize

Declared In

  scale

Brush scale of the series used to color the map.

@property (nonatomic, strong) NChartBrushScale *scale

Declared In

  tag

Tag of the series. You may use it as you want.

@property (nonatomic, assign) NSInteger tag

Declared In

NChartSeries.h

  hostsOnSX

Flag that determines if the series is hosted on the secondary X-axis. If YES, it will be drawn according to the secondary X-axis, if NO according to the normal X-axis. The secondary axis appears opposite the normal axis and is managed separately: it can have its own min and max; its own color settings and so on.

@property (nonatomic, assign) BOOL hostsOnSX

Declared In

NChartSeries.h

  hostsOnSY

Flag that determines if the series is hosted on the secondary Y-axis. If YES, it will be drawn according to the secondary Y-axis, if NO according to the normal Y-axis. The secondary axis appears opposite the normal axis and is managed separately: it can have its own min and max; its own color settings and so on.

@property (nonatomic, assign) BOOL hostsOnSY

Declared In

NChartSeries.h

  hostsOnSZ

Flag that determines if the series is hosted on the secondary Z-axis. If YES, it will be drawn according to the secondary Z-axis, if NO according to the normal Z-axis. The secondary axis appears opposite the normal axis and is managed separately: can have its own min and max; its own color settings and so on.

@property (nonatomic, assign) BOOL hostsOnSZ

Declared In

NChartSeries.h

  forceAbsolute

Flag that determines if the series forces absolute value axis. If YES, the series is drawn as if value axes type would be absolute, even if it’s not. If NO, the series is drawn according to the actual value axes type set in Cartesian system. The default value is NO.

@property (nonatomic, assign) BOOL forceAbsolute

Discussion

This property has effect for Cartesian system based series only. Otherwise it’s ignored.

  dataSource

Data source for the series.

@property (nonatomic, assign) id<NChartSeriesDataSource> dataSource

  dataSmoother

Data smoother used. The default value is nil (no data smoother used).

@property (nonatomic, strong) NChartDataSmoother *dataSmoother

Declared In

NChartSeries.h

  pointSelectionEnabled

Flag determining if the chart points can be selected by tap (YES) or not (NO). The default value is YES.If you do not want to select points by tap, it is better to disable selection, because it will save memory and boost the data updating.

@property (nonatomic, assign) BOOL pointSelectionEnabled

Discussion

This property works in conjuction with pointSelectionEnabled of NChart allowing to fine-tune the point selection for individual series.

Declared In

NChartSeries.h

  needsSeparateSums

Flag determining if in the additive value axis mode (when certesianSystem.valueAxesType = NChartValueAxesTypeAdditive) positive and negative values are added separately, so all positives are above zero and all negatives are below zero (YES), or all the values are just added together (NO). The default value is YES. Normally it’s reasonable to separate the sums (so keep this flag in its default state), but sometimes you may want to preserve the series order when they are stacked on the additive axis. In this case you may want to toggle this flag to NO.

@property (nonatomic, assign) BOOL needsSeparateSums
