详细描述

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...
}

注意： 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 .
