我使用 devexpress 制作了动态 3D 饼图。其良好的控制功能给我留下了深刻的印象。不过我还是有点沮丧。我希望我的饼图点具有我在代码中设置的不同颜色（用户稍后将使用某种形式的托盘或组合框进行更改，目前还不确定）。不幸的是，我似乎无法为我的数据系列的点找到颜色方法。

这是排除大量注释掉的尝试的代码：

Series series1 = new Series("Series1", ViewType.Pie3D);

        chartControl2.Series.Add(series1);

        series1.DataSource = chartTable;
        series1.ArgumentScaleType = ScaleType.Qualitative;
        series1.ArgumentDataMember = "names";
        series1.ValueScaleType = ScaleType.Numerical;
        series1.ValueDataMembers.AddRange(new string[] { "Value" });

        //series1.Label.PointOptions.PointView = PointView.ArgumentAndValues;
        series1.LegendPointOptions.PointView = PointView.ArgumentAndValues;
        series1.LegendPointOptions.ValueNumericOptions.Format = NumericFormat.Percent;
        series1.LegendPointOptions.ValueNumericOptions.Precision = 0;

        // Adjust the value numeric options of the series.
        series1.Label.PointOptions.ValueNumericOptions.Format = NumericFormat.Percent;
        series1.Label.PointOptions.ValueNumericOptions.Precision = 0;

        // Adjust the view-type-specific options of the series.
        ((Pie3DSeriesView)series1.View).Depth = 20;
        ((Pie3DSeriesView)series1.View).ExplodedPoints.Add(series1.Points[0]);
        ((Pie3DSeriesView)series1.View).ExplodedPoints.Add(series1.Points[1]);
        ((Pie3DSeriesView)series1.View).ExplodedPoints.Add(series1.Points[2]);
        ((Pie3DSeriesView)series1.View).ExplodedPoints.Add(series1.Points[3]);
        ((Pie3DSeriesView)series1.View).ExplodedDistancePercentage = 20;

        chartControl2.Legend.Visible = true;

所以我需要像 Chartcontrol2.series1.point[0].color = color.blue; 这样的东西像这样的东西。

原文

I've made a dynamic 3d piechart using devexpress. I'm really impressed with how good the control feature is. I've hit a little bit of a downer though.
I would like my pie chart points to have different colors that I set in code (this will later be changed by the user using some form of pallet or combo box, not sure yet). Unfortunatly I can't seem to get a color method for the points of my data series.

Here's the code excluding the mass of commented out attempts:

Series series1 = new Series("Series1", ViewType.Pie3D);

        chartControl2.Series.Add(series1);

        series1.DataSource = chartTable;
        series1.ArgumentScaleType = ScaleType.Qualitative;
        series1.ArgumentDataMember = "names";
        series1.ValueScaleType = ScaleType.Numerical;
        series1.ValueDataMembers.AddRange(new string[] { "Value" });

        //series1.Label.PointOptions.PointView = PointView.ArgumentAndValues;
        series1.LegendPointOptions.PointView = PointView.ArgumentAndValues;
        series1.LegendPointOptions.ValueNumericOptions.Format = NumericFormat.Percent;
        series1.LegendPointOptions.ValueNumericOptions.Precision = 0;

        // Adjust the value numeric options of the series.
        series1.Label.PointOptions.ValueNumericOptions.Format = NumericFormat.Percent;
        series1.Label.PointOptions.ValueNumericOptions.Precision = 0;

        // Adjust the view-type-specific options of the series.
        ((Pie3DSeriesView)series1.View).Depth = 20;
        ((Pie3DSeriesView)series1.View).ExplodedPoints.Add(series1.Points[0]);
        ((Pie3DSeriesView)series1.View).ExplodedPoints.Add(series1.Points[1]);
        ((Pie3DSeriesView)series1.View).ExplodedPoints.Add(series1.Points[2]);
        ((Pie3DSeriesView)series1.View).ExplodedPoints.Add(series1.Points[3]);
        ((Pie3DSeriesView)series1.View).ExplodedDistancePercentage = 20;

        chartControl2.Legend.Visible = true;

So I need something like chartcontrol2.series1.point[0].color = color.blue; something like this.
