Remarks

Chart legend

The set of series labels correspond to the chart legend.
Labels of series
Serial labels cannot be used with 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). Any changes made with <Chart>.Legend will take effect the next time <Chart>.Draw is called. You can change the position of the chart legend via a context menu.
Note To define series labels for "Scatter charts", use the <Chart>.ScatterSeriesLabel function. For more details, see Legends of a chart.

Manual legend positioning: grLegend without effect

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