Method Documentation

symbolForScatterPlot:recordIndex:

- (nullable CPTPlotSymbol *) symbolForScatterPlot:		(nonnull CPTScatterPlot *)	plot
recordIndex:		(NSUInteger)	idx

(Optional) Gets a single plot symbol for the given scatter plot. This method will not be called if -symbolsForScatterPlot:recordIndexRange: is also implemented in the datasource.

Parameters

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

Returns

The plot symbol to show for the point with the given index.

symbolsForScatterPlot:recordIndexRange:

- (nullable CPTPlotSymbolArray *) symbolsForScatterPlot:		(nonnull CPTScatterPlot *)	plot
recordIndexRange:		(NSRange)	indexRange

(Optional) Gets a range of plot symbols for the given scatter plot.

Parameters

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

Returns

An array of plot symbols.
