WPF Telerik散点图颜色

问题描述

我是WPF telerik技术框架的初学者。 我希望自定义颜色指向Telerik散点图中的点。但是，点的颜色没有改变。我该怎么办？我所做的事情有根本的错误吗？ 这是C＃代码

    var pallate = ColorPallate();

    var PS = new ScatterPointSeries();

    var pallaet = new ChartPalette();

    PaletteEntryCollection pall = new PaletteEntryCollection();

    for (int i = 0; i < data.GetLength(0); i++)

    {

        ScatterDataPoint point = new ScatterDataPoint();

        point.XValue = data[i,XAxisIndex];

        point.YValue = data[i,YAaxisIndex];

        int value = 0;

        if (!float.IsNaN(PredictedResult[i]))

            value = System.Convert.ToInt32(PredictedResult[i]);

        var filler = new PaletteEntry();
        filler.fill(pallate[value]);
        pall.Add(filler);
        PS.DataPoints.Add(point);



    }

    pallaet.SeriesEntries.Add(pall);

    this.Cross_Plot.Palette = pallaet;

其中ColorPallate（）提供自定义颜色调色板

private Brush[] ColorPallate()

{



    var pallate = new Brush[15];

    pallate[0] = new SolidColorBrush(Colors.Red);

    pallate[1] = new SolidColorBrush(Colors.Orange);

    pallate[2] = new SolidColorBrush(Colors.Green);

    pallate[3] = new SolidColorBrush(Colors.Pink);

    pallate[4] = new SolidColorBrush(Colors.Black);

    pallate[5] = new SolidColorBrush(Colors.brown);

    pallate[6] = new SolidColorBrush(Colors.Crimson);

    pallate[7] = new SolidColorBrush(Colors.DarkOrange);

    pallate[8] = new SolidColorBrush(Colors.ForestGreen);

    pallate[9] = new SolidColorBrush(Colors.Indigo);

    pallate[10] = new SolidColorBrush(Colors.DarkKhaki);

    pallate[11] = new SolidColorBrush(Colors.Purple);

    pallate[12] = new SolidColorBrush(Colors.Gold);

    pallate[13] = new SolidColorBrush(Colors.Rosybrown);

    pallate[14] = new SolidColorBrush(Colors.Gray);

    return pallate;

}

这是XMAL代码

                        </Style>

                    </telerik:ScatterPointSeries.DefaultVisualStyle>

                </telerik:ScatterPointSeries>







            </telerik:RadCartesianChart>



            <TextBlock Grid.Column="2" HorizontalAlignment="Left" Margin="131,37,0" textwrapping="Wrap" Text="Well points on X Axis" VerticalAlignment="Top" Width="248"/>

            <TextBlock Grid.Column="2" HorizontalAlignment="Left" Margin="389,35,0" textwrapping="Wrap" Text="Well points on Y axis" VerticalAlignment="Top" Width="243"/>
