Line Chart

Line series join points on a plot by straight lines, showing data trends at equal intervals. The following code example explains how to create a simple LineSeries using given data

xaml

<chart:LineSeries  XBindingPath="Year

ItemsSource="{Binding List}" YBindingPath="India"               

Interior="#4A4A4A"/>

<chart:LineSeries  XBindingPath="Year"     

ItemsSource="{Binding List}" YBindingPath="America"               

Interior="#4A4A4A"/>

c#

LineSeries series1 = new LineSeries()
{

    ItemsSource = new ViewModel().List,

    XBindingPath = "Year",

    YBindingPath = "India",

    Interior = new SolidColorBrush(Color.FromRgb(0x4A, 0x4A, 0x4A))

};

LineSeries series2 = new LineSeries()
{

    ItemsSource = new ViewModel().List,

    XBindingPath = "Year",

    YBindingPath = "America",

    Interior = new SolidColorBrush(Color.FromRgb(0x4A, 0x4A, 0x4A))

};

chart.Series.Add(series1);

chart.Series.Add(series2);

Step Line Chart

StepLineSeries plots horizontal and vertical lines to connect data points resulting in a step line progression. The following code illustrates how to initialize the StepLineSeries in chart.

xaml

<chart:StepLineSeries ItemsSource="{Binding Data}"  
                      
                      XBindingPath="XValue" 
                      
                      YBindingPath="YValue">
            
 </chart:StepLineSeries>

c#

StepLineSeries stepLine = new StepLineSeries();

stepLine.ItemsSource = new ViewModel().Data;

stepLine.XBindingPath = "XValue";

stepLine.YBindingPath = "YValue";

SteplineChart.Series.Add(stepLine);
