<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.

Series labels

The set of series labels correspond to the chart legend.
Series labels cannot be used in pie charts.
The Definition of the series labels is realized with the function grSeriesLabel.
The data defined by grSeriesLabel will be taken into account during the next call to grDraw.
The legend font can be modified by grLegendFont.
The grLegend function is used to indicate the presence and position of the legend (i.e. the set of serial labels).
Remark: To define series labels in "Scatter" charts, we recommend that you use grScatterSeriesLabel.


grSeriesLabel is equivalent to Legend.
