如何更改 Windows Phone 8.1 XAML ToolKit Chart 中 LineSeries 的颜色？

Question

I'm trying to set from the Code Behind a color of some line in Chart. I have searched for 3 hours how to do it and I couldn't find anything. Is it possible do to that? If it can't be do, please recommend another chart library where I can do that.

Thanks!

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;

Have you tried this? Try to set it when you get the line here

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

You may also try the following 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>

If anyone has problems, with Olaru Mircea solution in here

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;

just modify it like this:

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;

The first threw an exception for me, but after using double values, it worked fine.
