A legend names the series of a chart. Series come from the Legend field (for example Channel Type) or from several measures.

Reader actions

Action	Result
Click an item	Hides or shows that series.
Double-click an item	Shows only that series. Double-click it again to show all.

Value axes rescale to the series that remain, unless the axis has a fixed minimum or maximum. Stack totals are recalculated. Hidden series stay hidden when filters change or the chart is resized, but the report always opens with all series shown.

Settings

Select the chart and open Style → Legend:

Setting	What it does
Show	Shows or hides the legend.
Font	Font, size and colour of the items.
Pagination	On (default): items that do not fit are paged with arrows. Off: the legend wraps onto several lines.
Position	Where the legend sits around the plot.

On a pie chart, long legend names are shortened to fit and shown in full in the tooltip. If a wrapped legend would take more than half of the pie, it is paged instead.

Legend colours come from the page palette. Turn on Consistent member colors to give each member the same colour in every chart; see Colors and Color Schemes.
