Footer: IMapLegendHeader;
The Footer property returns lower legend text parameters.
Executing the example requires a form with the following components: the Button component named Button1, the MapBox component named MapBox1, and the UiMap component named UiMap1. UiMap1 is a data source for MapBox1. The UiMap1 component must have a connected map that contains a map indicator only.
The example is a handler of the OnClick event for the Button1 component.

Var
Map: IMap;
Layer: IMapLayer;
Legend: IMapLegend;
Footer: IMapLegendHeader;
Font: IGxFont;
Begin
Map := UiMap1.Map;
Legend := New DxMapLegend.Create As IMapLegend;
Map.View.Legend := Legend;
Legend.Visible := True;
// Stop legend rendering
Legend.BeginUpdate;
Layer := Map.Layers.FindByName("Regions");
Legend.Visual := Layer.Visuals.Item(0);
// Set parameters of legend bottom text
Footer := Legend.Footer;
// Set legend footer font color
Footer.Color := GxColor.FromName("Red");
Font := New GxFont.Create("Arial", 15, GxFontStyle.Bold);
// Set legend footer font
Footer.Font := Font;
// Set legend footer text
Footer.Text := "Legend";
// Resume legend rendering
Legend.EndUpdate;
End Sub Button1OnClick;
