如何将值(不仅仅是百分比)添加到 Excel 饼图?

How can I add the value (not just the percentage) to an Excel pie chart?

我有这个代码:

private void WriteChartSheet()
{
    _xlSheetChart = (Worksheet)_xlSheets.Item[2];

    if (_xlSheetChart != null)
    {
        _xlSheetChart.Name = ProduceUsageChartSheetName;
        // Contract vs. non-Contract pie chart 
        _xlSheetChart.Cells[1, 1] = "Contracted Items";
        _xlSheetChart.Cells[1, 2] = "Non-Contracted Items";
        _xlSheetChart.Cells[2, 1] = GetContractedItemsTotal();
        _xlSheetChart.Cells[2, 2] = GetNonContractedItemsTotal();

        ChartObjects xlCharts = (ChartObjects)_xlSheetChart.ChartObjects(Type.Missing);
        ChartObject contractChartObject = xlCharts.Add(0, 0, 300, 250); // left, top, width, height
        Chart contractChart = contractChartObject.Chart;

        Range chartRange = _xlSheetChart.get_Range("A1", "B2");
        contractChart.SetSourceData(chartRange, Missing.Value);
        contractChart.ChartType = XlChartType.xlPie;  //xl3DPie;
        contractChart.ApplyDataLabels(XlDataLabelsType.xlDataLabelsShowValue, XlDataLabelsType.xlDataLabelsShowLabel, true, false, false, true, false, true);
        . . .

...生成此饼图:

我非常喜欢它,但我也需要在馅饼块中打印价值(例如 "Contracted Items" 块中印有“361,779 美元”,另一块也有适当的价值) .我该怎么做?

在 C# 中,"true/false" 决定显示的值:

来自here

void ApplyDataLabels(
    XlDataLabelsType Type = XlDataLabelsType.xlDataLabelsShowValue,
    object LegendKey,
    object AutoText,
    object HasLeaderLines,
    object ShowSeriesName,
    object ShowCategoryName,
    object ShowValue,
    object ShowPercentage,
    object ShowBubbleSize,
    object Separator
)

因此,根据需要调整 TrueFalse

根据蝙蝠侠的信息进行实验,我想到了这个:

contractChart.ApplyDataLabels(XlDataLabelsType.xlDataLabelsShowValue, false, true, false, false, false, true, true, false, false);

...产生这个:

我希望百分比不要有前导“0”(它显示“045”和“055”而不是更明智和经济的“45”和“55”),但我可以生活和他们在一起。
