如何在条形图中显示每个绘图区域的百分比值 OfficeOpenXML 或 EPPlus C#？ [重复]

Question

我有堆叠条形图，因为我想显示每个标签的百分比（PDD1 标签为 80%）。

所以我添加了百分比记录，但无法从图表中隐藏并显示在每个标签区域的顶部中间。

我尝试了一些文章解决方案（https://stackoverflow.com/a/9036445/11010986），但我在 OfficeOpenXml.Drawing.Chart 中看不到 LoadEntries 选项

chart1.Legend.LoadEntries(chart1.Legend.LegendEntries().Count).Delete()

我看到了条目选项，但它是只读的。

C# 代码块：

dynamic DataList5 = new
{
    label = new List<string>() { "PDD1", "PDD2", "PDD3" },
    modeler = new { Category1 = new List<int>() { 1, 1, 1 }, Category2 = new List<int>() { 0, 0, 0 } },
    tester = new { Category1 = new List<int>() { 2, 2, 2 }, Category2 = new List<int>() { 2, 2, 2 } },
    percentage = new List<int>() { 150, 200, 10 }
};


if (DataList5.label.Count > 0)
{
    int j = 0;
    for (int i = 0; i < DataList5.label.Count * 2; i++)
    {
        if (i % 2 == 0)
        {
            ws2.Cells[i + 2, 2].Value = DataList5.label[j];
            ws2.Cells[i + 2, 3].Value = "Category 1";
            ws2.Cells[i + 2, 4].Value = DataList5.modeler.Category1[j];
            ws2.Cells[i + 2, 5].Value = DataList5.tester.Category1[j];
            ws2.Cells[i + 2, 6].Value = DataList5.percentage[j];
        }
        else
        {
            ws2.Cells[i + 2, 3].Value = "Category 2";
            ws2.Cells[i + 2, 4].Value = DataList5.modeler.Category2[j];
            ws2.Cells[i + 2, 5].Value = DataList5.tester.Category2[j];
            j++;
        }
    }
}
else
{
    ws2.Cells[2, 2].Value = "No Data Found";
}
var chart1 = ws1.Drawings.AddChart("chart1", eChartType.ColumnStacked);
chart1.SetPosition(1, 0, 0, 0);
chart1.SetSize(1800, 400);
chart1.Style = eChartStyle.Style12;

if (DataList5.label.Count > 0)
{
    var series1 = chart1.Series.Add(ws2.Cells["D2:D" + (DataList5.label.Count * 2 + 1)], ws2.Cells["B2:C" + (DataList5.label.Count * 2 + 1)]);
    var series2 = chart1.Series.Add(ws2.Cells["E2:E" + (DataList5.label.Count * 2 + 1)], ws2.Cells["B2:C" + (DataList5.label.Count * 2 + 1)]);
//percentage series
    //var series3 = chart1.Series.Add(ws2.Cells["F2:F" + (DataList5.label.Count * 2 + 1)], ws2.Cells["B2:C" + (DataList5.label.Count * 2 + 1)]);


    series1.Fill.Color = Color.FromArgb(255, 0, 112, 192);
    series2.Fill.Color = Color.FromArgb(255, 239, 125, 49);

//Show percentage for each PDD1 label
    ////chart1.Legend.LoadEntries(chart1.Legend.LegendEntries().Count).Delete();

    series1.Header = "Modeler";
    series2.Header = "Tester";
    //series3.Header = "Percentage";

}
else
{
    var series1 = chart1.Series.Add(ws2.Cells["B2:C" + (DataList1.label.Count + 1)], ws2.Cells["B2:C" + (DataList1.label.Count + 1)]);
}

chart1.Title.Text = "Stacked bar chart example";

有人知道 C# EPPlus 或 OfficeOpenXML 中的解决方案吗？

Answer 1

因此，只需使用 Excel 中提供的标准图表并添加数据标签即可：
