如何更改 Windows Phone 8.1 XAML ToolKit Chart 中 LineSeries 的顏色？

Question

我正在嘗試從代碼背后設置圖表中某行的顏色。 我已經搜索了 3 個小時如何去做，但我找不到任何東西。 有可能這樣做嗎？ 如果做不到，請推薦另一個我可以做到的圖表庫。

謝謝！

XAML

<Charting:Chart Title="Name" x:Name="LineChart" HorizontalAlignment="Left" VerticalAlignment="Center"  Width="510" Height="450">
        <Charting:LineSeries Title="PB" IndependentValuePath="Name" DependentValuePath="Amount" IsSelectionEnabled="True"/>
        <Charting:LineSeries Title="Oil" IndependentValuePath="Name" DependentValuePath="Amount" IsSelectionEnabled="True"/>
    </Charting:Chart>

WPF

Random rand = new Random();
        List<FinancialStuff> financialStuffList = new List<FinancialStuff>();
        for (int i = 0; i < 30; i++ )
            financialStuffList.Add(new FinancialStuff() { Name = Convert.ToString(i), Amount = rand.Next(0, 200) });

        (LineChart.Series[0] as LineSeries).ItemsSource = financialStuffList;

        for (int i = 0; i < 30; i++)
            financialStuffList[i].Amount = rand.Next(0, 50);
        (LineChart.Series[1] as LineSeries).ItemsSource = financialStuffList;



public class FinancialStuff
    {
        public string Name { get; set; }
        public int Amount { get; set; }
    }

Answer 1

 Style style = new Style(typeof(Control));
 style.Setters.Add(new Setter(Control.BackgroundProperty, new  SolidColorBrush(Colors.Red)));
 style.Setters.Add(new Setter(Control.HeightProperty, 5));
 style.Setters.Add(new Setter(Control.WidthProperty, 5));
 series.DataPointStyle = style;

你有嘗試過嗎？ 當您到達此處時嘗試設置它

 (LineChart.Series[0] as LineSeries).DataPointStyle = style;  

您也可以嘗試以下XAML：

<charting:LineSeries.DataPointStyle>
   <Style TargetType="charting:LineDataPoint">
       <Setter Property="Width" Value="17" />
       <Setter Property="Height" Value="17" />
       <Setter Property="Background" Value="Lime"/>
   </Style>
</charting:LineSeries.DataPointStyle>

如果有人有問題，請在此處使用 Olaru Mircea 解決方案

Style style = new Style(typeof(Control));
 style.Setters.Add(new Setter(Control.BackgroundProperty, new  SolidColorBrush(Colors.Red)));
 style.Setters.Add(new Setter(Control.HeightProperty, 5));
 style.Setters.Add(new Setter(Control.WidthProperty, 5));
 series.DataPointStyle = style;

只需像這樣修改它：

Style style = new Style(typeof(Control));
 style.Setters.Add(new Setter(Control.BackgroundProperty, new  SolidColorBrush(Colors.Red)));
 style.Setters.Add(new Setter(Control.HeightProperty, 5.0));
 style.Setters.Add(new Setter(Control.WidthProperty, 5.0));
 series.DataPointStyle = style;

第一個為我拋出異常，但在使用雙精度值后，它工作正常。
