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 图例 type properties can be attached to the ChartView type. For example:
ChartView { legend.visible: true legend.alignment: Qt.AlignBottom // Add a few series... }
