c# - 如何更改图表控件中各个列的颜色？

Question

我有一个 ascx 页面，代码后面的代码如下所示

private void CreateProjectsByRAG()
    {
        foreach (ProjectStatistic PR in repository.GetProjectByRAG())
        {
            ProjectsByProjectTypePieChart.Series["series"].Points.AddXY(PR.Name, PR.Value);
        }

        ProjectsByProjectTypePieChart.Titles["Title1"].Text = "Projects by RAG Status";
        ProjectsByProjectTypePieChart.Series["series"].ChartType = SeriesChartType.Column;// Set the Pie width
        ProjectsByProjectTypePieChart.Series["series"].Color = System.Drawing.Color.FromArgb(255, 0, 0);
    }

这会产生一个看起来像这样的图表

但我想单独为列着色，使它们看起来像这样，我还希望列的颜色与其标签相同（所以不是随机的）。

另外，如何对列进行排序？这样我就可以按照绿色，琥珀色，红色的顺序来拥有它们

代码是

foreach (ProjectStatistic PR in repository.GetProjectByRAG())
        {
            int index = ProjectsByProjectTypePieChart.Series["series"].Points.AddXY(PR.Name, PR.Value);
            if (PR.Name == "Green")
            { 
                ProjectsByProjectTypePieChart.Series["series"].Points[index].Color = System.Drawing.Color.Green;
            }

            if (PR.Name == "Amber")
            {
                ProjectsByProjectTypePieChart.Series["series"].Points[index].Color = System.Drawing.Color.Yellow;
            }

            if (PR.Name == "Red")
            {
                ProjectsByProjectTypePieChart.Series["series"].Points[index].Color = System.Drawing.Color.Red;
            }

        }
