PercentBarSeries QML Type

以每类数据的百分比显示一系列分类数据。更多

Import Statement:	`import QtCharts 2.9`
In C++:	QPercentBarSeries
Inherits:	AbstractBarSeries

所有成员（包括继承成员）的列表

详细说明

数据绘制为一系列大小一致的垂直堆叠条形图，每个类别一个条形图。添加到系列中的每个条形集都会为每个堆叠条形提供一个段。分段大小与分段值占堆栈中所有分段总值的百分比相对应。数值为零的条形图不会绘制。

下面的 QML 代码片段展示了如何创建一个简单的百分比条形图：

ChartView {
    title: "Percent Bar Chart"
    anchors.fill: parent
    legend.alignment: Qt.AlignBottom
    antialiasing: true

    PercentBarSeries {
        axisX: BarCategoryAxis { categories: ["2007", "2008", "2009", "2010", "2011", "2012" ] }
        BarSet { label: "Bob"; values: [2, 2, 3, 4, 5, 6] }
        BarSet { label: "Susan"; values: [5, 1, 2, 4, 1, 7] }
        BarSet { label: "James"; values: [3, 5, 8, 13, 5, 8] }
    }
}
