Asp.net mvc 在devexpress图表中更改颜色

我正在MVC项目中使用Devexpress绘制饼图

在默认情况下，我的图表会生成三种颜色，如下所示

但是我的客户对它的颜色不满意，希望我更改与我们的应用程序背景相匹配的颜色，所以请帮助我，如何做到这一点

提前谢谢。 这是我的密码

    settings.Name = "chart";
    settings.Width = 600;
    settings.Height = 250;
    settings.BorderOptions.Visible = false;

    Series series1 = new Series("Type", DevExpress.XtraCharts.ViewType.Pie3D);
    settings.Series.Add(series1);
    series1.ArgumentScaleType = ScaleType.Qualitative;
    series1.ArgumentDataMember = "ClassName";
    series1.ValueScaleType = ScaleType.Numerical;
    series1.ValueDataMembers.AddRange(new string[] { "PercentageValues" });


    series1.LegendPointOptions.PointView = PointView.ArgumentAndValues;
    series1.LegendPointOptions.ValueNumericOptions.Format = NumericFormat.Percent;
    series1.LegendPointOptions.ValueNumericOptions.Precision = 0;
    series1.Label.ResolveOverlappingMode = ResolveOverlappingMode.Default;
    series1.Label.Visible = false;

可以设置图表控件的主题和调色板属性。按照以下链接访问devexpress文档。尽管这些示例引用了winform应用程序，但它们仍然可以在asp.net mvc控件中使用

请参考以下代码。我已经成功地实现了为rangebar提供自定义颜色的相同功能。我想这也适用于你的案子

 settings.CustomDrawSeriesPoint = (s, ev) =>
    {
        BarDrawOptions drawOptions = ev.SeriesDrawOptions as BarDrawOptions;

        if (drawOptions == null)
            return;

        Color colorInTarget = Color.Blue;
        double x = ev.SeriesPoint.Values[0];
        double y = ev.SeriesPoint.Values[1];


        if (x == 0)
        {  //Do starting
            colorInTarget = Color.FromArgb(159,125, 189);
        }
        else{
            //Red - price Increase
            // Green price Decrease
            if (y > previousYValue)
            {
                colorInTarget = Color.Red; ;
            }
            else
            {
                colorInTarget = Color.Green;
            }
        }


        previousYValue = y;

        drawOptions.Color = colorInTarget;
        drawOptions.FillStyle.FillMode = FillMode.Solid;
        drawOptions.Border.Color = Color.Transparent;



    };
