Remarks

Chart legend

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.
grLegend indicates the presence and position of the legend (i. e. all series labels). The modifications performed by grLegend will be taken into account during the next call to grDraw. You can change the position of the chart legend via a context 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

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