Question

如何在我的Excel饼图上创建自定义颜色？我的饼图有5个切片。以下是我的源代码。

using Excel = Microsoft.Office.Interop.Excel;
Excel.Range chartRange;

Excel.ChartObjects xlCharts = (Excel.ChartObjects)xlWorkSheet.ChartObjects(Type.Missing);
Excel.ChartObject myChart = (Excel.ChartObject)xlCharts.Add(10, 80, 500, 350);
Excel.Chart chartPage = myChart.Chart;

chartRange = xlWorkSheet.get_Range("A3", "B7");            
chartPage.ChartStyle = 209;
chartPage.HasTitle = true;
chartPage.ChartTitle.Text = "HeaderText Title";
chartPage.SetSourceData(chartRange, misValue);            
chartPage.ChartType = Excel.XlChartType.xl3DPieExploded;
chartPage.Elevation = 35;
chartPage.ApplyDataLabels(Excel.XlDataLabelsType.xlDataLabelsShowLabelAndPercent ,false, true, true, false, true, false, true, true, Separator:System.Environment.NewLine);

xlWorkBook.SaveAs(saveAsLocation);
xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();

Answer 1

您可以像这样更改饼图中每个点的// $all= array ( 0 => array ( 1 => array ( 'ED' => 60, 'EN' => 64, 'MT' => 44, 'MZ' => 47, ), ), 1 => array ( 2 => array ( 'ED' => 43, 'EN' => 50, 'MT' => 92, 'MZ' => 90, ), ), ) //$fscores= array ( 1 => array ( 'score' => 215, 'farray' => true, 'tarray' => true, ), 2 => array ( 'score' => 275, 'farray' => false, 'tarray' => true, ), )：

ColorIndex属性可以包含0到56之间的有效整数参数，用于生成颜色。

Answer 2

我相信您可以更改系列点格式的ForeColor属性。类似的东西：

var series = (Excel.SeriesCollection)chartPage.SeriesCollection();
var points = (Excel.Points)series.Item(1).Points();
points.Item(1).Format.Fill.ForeColor.RGB = (int)Excel.XlRgbColor.rgbRed;
points.Item(2).Format.Fill.ForeColor.RGB = (int)Excel.XlRgbColor.rgbBlue;

......等等。
