wpf不同颜色的面积图？

Question

我是一个沉思MS工具包图表,无法弄清楚如何改变区域的颜色.我需要动态填充图表,这意味着我不知道区域图表将有多少部分.

这是我的代码.

var a = new AreaSeries
{
  Title = "a",
  IndependentValuePath = "Key",
  DependentValuePath = "Value",
  Background = Brushes.Plum
};

我试图改变前景和背景,没有骰子.

mcChart.Series.Add(a);

a = new AreaSeries
{
  Title = "b",
  IndependentValuePath = "Key",
  DependentValuePath = "Value",
  Background = Brushes.Peru
};

mcChart.Series.Add(a);

填写图表.

((AreaSeries)mcChart.Series[0]).ItemsSource = new[]
{
  new KeyValuePair<string, int>("1", 100),
  new KeyValuePair<string, int>("2", 180),
  new KeyValuePair<string, int>("3", 110),
  new KeyValuePair<string, int>("4", 95),
  new KeyValuePair<string, int>("5", 40),
  new KeyValuePair<string, int>("6", 95)
};

((AreaSeries)mcChart.Series[1]).ItemsSource = new[]
{
  new KeyValuePair<string, int>("1", 150),
  new KeyValuePair<string, int>("2", 280),
  new KeyValuePair<string, int>("3", 310),
  new KeyValuePair<string, int>("4", 195),
  new KeyValuePair<string, int>("5", 340),
  new KeyValuePair<string, int>("6", 195)
};

我是wpf的新手,我无法弄清楚这有什么问题.

这是XAML

<chartingToolkit:Chart 
  Width="600" Height="450"
  Name="mcChart" 
  Background="LightBlue"
  Foreground="DarkBlue"
  Title="Area Chart">                
</chartingToolkit:Chart>

如何更改区域a和区域b的颜色.现在,即使我设置了背景和前景,它们也是默认的颜色.

谢谢.

你可以使用这样的Chart.Palette属性:

<Grid>
    <charting:Chart>
        <charting:Chart.Palette>
            <visualizationToolkit:ResourceDictionaryCollection>
                <ResourceDictionary>
                    <Style x:Key="DataPointStyle" TargetType="Control">
                        <Setter Property="Background" Value="MistyRose"/>
                    </Style>
                </ResourceDictionary>
                <ResourceDictionary>
                    <Style x:Key="DataPointStyle" TargetType="Control">
                        <Setter Property="Background" Value="AliceBlue"/>
                    </Style>
                </ResourceDictionary>
            </visualizationToolkit:ResourceDictionaryCollection>
        </charting:Chart.Palette>
        <charting:AreaSeries Title="Series 1"/>
        <charting:AreaSeries Title="Series 2"/>
    </charting:Chart>
</Grid>
