<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.
