Remarks

The LegendItem class represents a legend item, which can be either a default or custom item:

• Default legend items are automatically inserted into the legend for either data series or data points. Default entries for pie and doughnut charts represent the plotted data points, whereas entries for all other chart types represent the plotted series. By default, these legend entries use the data point or series color for the symbol color, and the name of the series or data point for the legend item text. Default legend items can be customized or deleted at run time by using the CustomizeLegend event of the Chart control.

• Custom legend items have user-defined text, symbol color, and so forth. Unlike the default entries, they are not connected with the plotted data. Custom legend items can be added at either design time or run time, using the CustomItems property of the Legend object.

Legend symbols can be rectangles, lines or markers, depending on the ImageStyle property setting of a LegendItem object.

The text of a custom legend item is determined by the Name property.
