Detailed Description

A range plot data source.

Method Documentation

barLineStyleForRangePlot:recordIndex:

- (nullable CPTLineStyle *) barLineStyleForRangePlot:		(nonnull CPTRangePlot *)	plot
recordIndex:		(NSUInteger)	idx

(Optional) Gets a bar line style for the given range plot. This method will not be called if -barLineStylesForRangePlot:recordIndexRange: is also implemented in the datasource.

Parameters

plot	The range plot.
idx	The data index of interest.

Returns

The bar line style for the bar with the given index. If the data source returns nil, the default line style is used. If the data source returns an NSNull object, no line is drawn.

barLineStylesForRangePlot:recordIndexRange:

- (nullable CPTLineStyleArray *) barLineStylesForRangePlot:		(nonnull CPTRangePlot *)	plot
recordIndexRange:		(NSRange)	indexRange

(Optional) Gets a range of bar line styles for the given range plot.

Parameters

plot	The range plot.
indexRange	The range of the data indexes of interest.

Returns

An array of line styles.

barWidthForRangePlot:recordIndex:

- (nullable NSNumber *) barWidthForRangePlot:		(nonnull CPTRangePlot *)	plot
recordIndex:		(NSUInteger)	idx

(Optional) Gets a bar width for the given range plot. This method will not be called if -barWidthsForRangePlot:recordIndexRange: is also implemented in the datasource.

Parameters

plot	The range plot.
idx	The data index of interest.

Returns

The bar width for the bar with the given index. If the data source returns nil, the default barWidth is used.

barWidthsForRangePlot:recordIndexRange:

- (nullable CPTNumberArray *) barWidthsForRangePlot:		(nonnull CPTRangePlot *)	plot
recordIndexRange:		(NSRange)	indexRange

(Optional) Gets an array of bar widths for the given range plot.

Parameters

plot	The range plot.
indexRange	The range of the data indexes of interest.

Returns

An array of bar widths.
