grLegend(<Chart name> , <Position>)
<Chart name>: Control name or character string
Name of the chart to be used. This name corresponds to:
  • the chart name defined through programming with grCreate.
  • the name of Chart control found in the window editor, page editor or report editor.
<Position>: entier

Remarks

Legend of a graph

The set of series labels correspond to the chart legend.
Labels of series
Series labels cannot be used in Pie charts.
Series labels are defined with grSeriesLabel.
The legend font can be changed with grLegendFont.
The grLegend function is used to indicate the presence and position of the legend (i.e. the set of serial labels). The modifications performed by grLegend will be taken into account during the next call to grDraw. The position of the chart legend can be modified from a popup menu.
Remark: To define series labels in "Scatter" charts, we recommend that you use grScatterSeriesLabel. For more details, see Legends of a chart.

Manual positioning of legend: grLegend without effect

Manual positioning has no effect if the legend is positioned manually ("grLegend" in the chart legend window).
