    Implement one of the following methods in your datasource:

    -(NSArray *)symbolsForScatterPlot:(CPScatterPlot *)plot recordIndexRange:(NSRange)indexRange;
-(CPPlotSymbol *)symbolForScatterPlot:(CPScatterPlot *)plot recordIndex:(NSUInteger)index;

    You can create as many different plot symbols as you need. Simply return the correct one for each point.
