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 <Chart>.SeriesLabel.
The legend font can be changed with <Chart>.LegendFont.
<Chart>.Legend indicates the presence and position of the legend (i. e. all series labels). The modifications performed by <Chart>.Legend will be taken into account during the next call to <Chart>.Draw. 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 <Chart>.ScatterSeriesLabel. For more details, see Legends of a chart.

Manual positioning of legend: grLegend without effect

<Chart>.Legend has no effect if the legend is positioned manually ("Manual positioning" in the chart legend window).
