<Chart control>.SeriesLabel(<Series number> , <Label>)
<Chart control>: Control name

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 <Chart>.SeriesLabel.
The data defined by <Chart>.SeriesLabel will be taken into account during the next call to <Chart>.Draw.
The legend font can be changed with <Chart>.LegendFont.
<Chart>.Legend 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 <Chart>.ScatterSeriesLabel.


The <Chart>.SeriesLabel function is equivalent to the Legend property.
