    Plot symbols are an optional part of the scatter plot. There are lots of examples throughout the example apps included with Core Plot, including a demo in the Plot Gallery that shows all of the predefined plot symbol shapes.

    You can have the scatter plot show the same symbol at every data point by setting the plotSymbol property. If you want different symbols at different points, implement one of the following datasource methods:

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

    Each plot symbol has a fill and lineStyle that determine the inside fill and the border line style. These are standard CPTFill and CPTLineStyle objects used throughout Core Plot.
