## Detailed Description

A legend is a graphical object that displays the legend of a chart. The legend state is updated by the ChartView type when series change. The Legend type properties can be attached to the ChartView type. For example:

     ChartView {
         legend.visible: true
         legend.alignment: Qt.AlignBottom
         // Add a few series...
     }

Note: There is no QML API available for modifying legend markers. Markers can be modified by creating a custom legend, as illustrated by Qml Custom Example.

## Property Documentation

`Legend.MarkerShapeFromSeries` | Legend marker shape is determined by the series

This property was introduced in Qt 5.9.
