Remarks Legend of a graph The set of series labels correspond to the chart legend.
Series labels cannot be used in Pie charts. 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. Manual positioning of legend: grLegend without effect Manual positioning has no effect if the legend is positioned manually ("grLegend" in the chart legend window).
