MVC プロジェクトで Devexpress を使用して円グラフを描画しています。

デフォルトでそれをしている間、以下のように私のチャートは3色で生成されました

しかし、私のクライアントはその色に満足しておらず、アプリケーションの背景に合わせて色を変更することを望んでいたので、これを行う方法を教えてください。

前もって感謝します。これが私のコードです。

    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;

チャート コントロールのテーマとパレットのプロパティを設定できます。以下のリンクに従って、devexpress のドキュメントを参照してください。例は winform アプリケーションを参照していますが、asp.net mvc コントロールでも使用できます。

    // Define the chart's appearance and palette.
barChart.AppearanceName = "Dark";
barChart.PaletteName = "Opulent";
