c# - パイ片を入れるのに十分な大きさのパイ片に、そうでないパイ片と一緒にラベルを追加するにはどうすればよいですか?

Question

この Excel チャートを生成する単純な偽のデータがあります。

これはコードです：

object misValue = System.Reflection.Missing.Value;
//add data 
_xlSheet.Cells[11, 11] = "";
_xlSheet.Cells[11, 12] = "Student1";
_xlSheet.Cells[11, 13] = "Student2";
_xlSheet.Cells[11, 14] = "Student3";

_xlSheet.Cells[12, 11] = "Term1";
_xlSheet.Cells[12, 12] = "80";
_xlSheet.Cells[12, 13] = "65";
_xlSheet.Cells[12, 14] = "45";

_xlSheet.Cells[13, 11] = "Term2";
_xlSheet.Cells[13, 12] = "78";
_xlSheet.Cells[13, 13] = "72";
_xlSheet.Cells[13, 14] = "60";

_xlSheet.Cells[14, 11] = "Term3";
_xlSheet.Cells[14, 12] = "82";
_xlSheet.Cells[14, 13] = "80";
_xlSheet.Cells[14, 14] = "65";

_xlSheet.Cells[15, 11] = "Term4";
_xlSheet.Cells[15, 12] = "75";
_xlSheet.Cells[15, 13] = "82";
_xlSheet.Cells[15, 14] = "68";

Excel.Range chartRange;

Excel.ChartObjects xlCharts = (Excel.ChartObjects)_xlSheet.ChartObjects(Type.Missing);
Excel.ChartObject myChart = (Excel.ChartObject)xlCharts.Add(468, 160, 348, 268); //10, 80, 300, 250);
Excel.Chart chartPage = myChart.Chart;

chartRange = _xlSheet.get_Range("K11", "O15");
chartPage.SetSourceData(chartRange, misValue);
chartPage.ChartType = Excel.XlChartType.xlPieExploded; // xl3DPie; xlPie; xlColumnClustered;

適切なパイ片を指す矢印で、それらを含むのに十分な大きさのパイ片にラベルを追加し、そうでないものと一緒にラベルを追加するにはどうすればよいですか?

Answer 1

ラベルの追加は次のように簡単です。

chart.ApplyDataLabels(Excel.XlDataLabelsType.xlDataLabelsShowPercent, Excel.XlDataLabelsType.xlDataLabelsShowLabel, true, false, false, true, false, true);

文脈では：

object misValue = System.Reflection.Missing.Value;

_xlSheet.Cells[12, 11] = "John";
_xlSheet.Cells[12, 12] = "80";
_xlSheet.Cells[12, 13] = "165";
_xlSheet.Cells[12, 14] = "45";

_xlSheet.Cells[13, 11] = "Paul";
_xlSheet.Cells[13, 12] = "78";
_xlSheet.Cells[13, 13] = "72";
_xlSheet.Cells[13, 14] = "6";

_xlSheet.Cells[14, 11] = "George";
_xlSheet.Cells[14, 12] = "182";
_xlSheet.Cells[14, 13] = "180";
_xlSheet.Cells[14, 14] = "165";

_xlSheet.Cells[15, 11] = "Ringo";
_xlSheet.Cells[15, 12] = "7";
_xlSheet.Cells[15, 13] = "8";
_xlSheet.Cells[15, 14] = "6";

Excel.Range chartRange;

Excel.ChartObjects xlCharts = 
(Excel.ChartObjects)_xlSheet.ChartObjects(Type.Missing);
Excel.ChartObject chartObj = (Excel.ChartObject)xlCharts.Add(468, 160, 348, 268);
Excel.Chart chart = chartObj.Chart;

chartRange = _xlSheet.Range[_xlSheet.Cells[12, 11], _xlSheet.Cells[15, 14]];
chart.SetSourceData(chartRange, misValue);
chart.ChartType = Excel.XlChartType.xlPieExploded; 
chart.ApplyDataLabels(Excel.XlDataLabelsType.xlDataLabelsShowPercent, 
Excel.XlDataLabelsType.xlDataLabelsShowLabel, true, false, false, true, false, true);
