百分比堆积条形图

百分比堆积条形图 (100%-堆积条形图) 是由 FullStackedBarSeriesView 对象来表示的，此对象属于条形和柱状系列视图。这种视图为每个类别使用单个堆积条形来显示所有系列。每个条形的高度始终是图表图象的全部高度 (即 1)。系列取值被显示为每个条形的百分比。

在下面的插图中显示了一个百分比堆积条形图。注意，这种图表类型基于 XYDiagram，因此可以被旋转，从而垂直地或水平地显示图表。

注意
百分比堆积条形图可以显示包含正值或负值数据点的系列。但是，有正值的系列只能与其他包含正值的系列相堆积；有负值的系列与其他包含负值的系列相堆积。注意，如果系列同时包含正值和负值数据点，那么它被作为有正值的系列进行处理，而它的所有负值都被视为零。

注意

百分比堆积条形图可以显示包含正值或负值数据点的系列。但是，有正值的系列只能与其他包含正值的系列相堆积；有负值的系列与其他包含负值的系列相堆积。

注意，如果系列同时包含正值和负值数据点，那么它被作为有正值的系列进行处理，而它的所有负值都被视为零。

下表列出了这种图表类型的主要特征。

特征	取值
系列视图类型	FullStackedBarSeriesView
图象类型	2D- XYDiagram
每个数据点的参数个数	1
每个数据点的取值个数	1

注意
要获得关于哪些图表类型可以与百分比堆积条形图组合使用的信息，请参阅组合使用不同的系列视图文档。

下面的示例演示了在运行时刻如何创建 ChartControl (拥有两个 FullStackedBarSeriesView 类型的系列)，并把图表添加到窗体中。在继续本示例之前，首先要在 Visual Studio 中创建一个 Windows 窗体应用程序，并把所有必需的程序集包含到项目的“引用”列表中。

然后，把下列代码添加到 Form.Load 事件处理程序。

C#	复制代码
using DevExpress.XtraCharts; // ... private void Form1_Load(object sender, EventArgs e) { // Create a new chart. ChartControl FullStackedBarChart = new ChartControl(); // Create two full-stacked bar series. Series series1 = new Series("Series 1", ViewType.FullStackedBar); Series series2 = new Series("Series 2", ViewType.FullStackedBar); // Add points to them. series1.Points.Add(new SeriesPoint(1, 10)); series1.Points.Add(new SeriesPoint(2, 12)); series1.Points.Add(new SeriesPoint(3, 14)); series1.Points.Add(new SeriesPoint(4, 17)); series2.Points.Add(new SeriesPoint(1, 15)); series2.Points.Add(new SeriesPoint(2, 18)); series2.Points.Add(new SeriesPoint(3, 25)); series2.Points.Add(new SeriesPoint(4, 33)); // Add both series to the chart. FullStackedBarChart.Series.AddRange(new Series[] { series1, series2 }); // Set the numerical argument scale types for the series, // as it is qualitative, by default. series1.ArgumentScaleType = ScaleType.Numerical; series2.ArgumentScaleType = ScaleType.Numerical; // Access the view-type-specific options of the series. ((FullStackedBarSeriesView)series1.View).BarWidth = 0.4; // Access the type-specific options of the diagram. ((XYDiagram)FullStackedBarChart.Diagram).EnableAxisXZooming = true; // Hide the legend (if necessary). FullStackedBarChart.Legend.Visible = false; // Add the chart to the form. FullStackedBarChart.Dock = DockStyle.Fill; this.Controls.Add(FullStackedBarChart); }

C#

复制代码

using DevExpress.XtraCharts;
// ...

private void Form1_Load(object sender, EventArgs e) {
    // Create a new chart.
    ChartControl FullStackedBarChart = new ChartControl();

    // Create two full-stacked bar series.
    Series series1 = new Series("Series 1", ViewType.FullStackedBar);
    Series series2 = new Series("Series 2", ViewType.FullStackedBar);

    // Add points to them.
    series1.Points.Add(new SeriesPoint(1, 10));
    series1.Points.Add(new SeriesPoint(2, 12));
    series1.Points.Add(new SeriesPoint(3, 14));
    series1.Points.Add(new SeriesPoint(4, 17));

    series2.Points.Add(new SeriesPoint(1, 15));
    series2.Points.Add(new SeriesPoint(2, 18));
    series2.Points.Add(new SeriesPoint(3, 25));
    series2.Points.Add(new SeriesPoint(4, 33));

    // Add both series to the chart.
    FullStackedBarChart.Series.AddRange(new Series[] { series1, series2 });

    // Set the numerical argument scale types for the series,
    // as it is qualitative, by default.
    series1.ArgumentScaleType = ScaleType.Numerical;
    series2.ArgumentScaleType = ScaleType.Numerical;

    // Access the view-type-specific options of the series.
    ((FullStackedBarSeriesView)series1.View).BarWidth = 0.4;

    // Access the type-specific options of the diagram.
    ((XYDiagram)FullStackedBarChart.Diagram).EnableAxisXZooming = true;

    // Hide the legend (if necessary).
    FullStackedBarChart.Legend.Visible = false;

    // Add the chart to the form.
    FullStackedBarChart.Dock = DockStyle.Fill;
    this.Controls.Add(FullStackedBarChart);
