PointStyles provide a mechanism to mark specific data points with different visual attributes than other points of the same data series. PointStyles are contained by the PointStylesCollection. A PointStyle can be applied to an explicit data point that is selected by series and point indexes or to a data point that meets to specific conditions -such as: x maximum of series, y maximum of all data, and so on. The C1Chart programmer can also specify custom conditions using the Select event. A PointStyle contains the same set of visual properties as ChartDataSeries LineStyle, SymbolStyle and Offset. These properties describe the appearance of a data point that meets the PointStyle condition. A PointStyle can be shown as legend item.
