Displaying a Legend
The base class used to define a legend to be added to a given chart is the
IlvChartLegend class. This class inherits from the
IlvShadowRectangle class. Thus, the chart legend object is a graphic object just like the chart object and is positioned independently of the chart object.
A Legend Added to a Chart shows an example of a legend that has been added to a chart. This legend is composed of three legend items and is surrounded by a filled rectangle with a shadow.
A Legend Added to a Chart
The legend items that make up the legend are represented by instances of the
IlvChartLegendItem class. Each legend item is composed of two elements (see
Elements of a Legend Item):
The
graphic part illustrates the graphical representation of data with which the legend item is associated. For example, for data displayed by markers, the graphic part will show the marker with the same color and shape.
The
text part displays a description or a label for the represented data.
