Initializes the label of a data series in a chart.
Example of series label:
To display the label, use grLegend.
Reminder: By default, a chart has no label. For more details about the management of legends, labels, ... see Managing legends in the charts.
Linux Caution: A specific configuration is required to use this function in Linux. For more details, see The charts.
Example
// Initialize the "Sales" label of second data series in "MyChart"
grSeriesLabel("MyChart", 2, "Sales")
// Initialize the "Sales" label of second data series in CHART_MyChart
grSeriesLabel(CHART_MyChart, 2, "Sales")
Syntax
grSeriesLabel(<Chart name> , <Series number> , <Label>)
<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 the Chart control in the window, page or report editor.
Android Only Chart controls are available.
PHP Only the interactive Chart controls are available.
<Series number>: Integer
Number of the series for which a label will be initialized.
<Label>: Character string
Caption of label to initialize.
Remarks

Series labels

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

Equivalence

The grSeriesLabel function is equivalent to the Legend property.
