如何使用 MigraDoc 创建饼图

问题描述

我不断收到此错误：

ChartType 'Pie2D' not valid for combination of charts.

但找不到任何合适的示例/文档。

解决方法

以下是适用于 MigraDoc 1.50 的示例：

/// <summary>
/// Defines the charts page.
/// </summary>
public static void DefineCharts(Document document)
{
    var paragraph = document.LastSection.AddParagraph("Chart Overview","Heading1");
    paragraph.AddBookmark("Charts");

    document.LastSection.AddParagraph("Sample Chart","Heading2");

    Chart chart = new Chart(ChartType.Pie2D);
    chart.Width = Unit.FromCentimeter(16);
    chart.Height = Unit.FromCentimeter(12);
    Series series = chart.SeriesCollection.AddSeries();
    series.Add(new double[] { 1,5,11,-3,20 });

    XSeries xseries = chart.XValues.AddXSeries();
    xseries.Add("Production","Lab","Licenses","Taxes","Insurances");
    //chart.Legend.Docking = DockingType.Right;

    chart.DataLabel.Type = DataLabelType.Percent;
    chart.DataLabel.Position = DataLabelPosition.OutsideEnd;

    document.LastSection.Add(chart);
}
