The Line Chart displays trends over a period of time by connecting different data points in a series with a straight line. It treats the input as categorical information that is evenly spaced along the X-axis.

You can create the Line Chart by setting the ChartType property to Line in XAML, at design-time, or using code.

To create the stacking WPF Line Chart, you need to set the Stacking property to Stacked or Stacked100pc.

Below is the code that implements the aforementioned example:

<c1:C1FlexChart x:Name="flexChart" 
                BindingX="Country" 
                ItemsSource="{Binding DataContext.Data}" 
                ChartType="Line">
    <c1:C1FlexChart.Series>
        <c1:Series SeriesName="Sales" 
                   Binding="Sales"/>
        <c1:Series SeriesName="Expenses" 
                   Binding="Expenses"/>
    </c1:C1FlexChart.Series>
</c1:C1FlexChart>

flexChart.ChartType = C1.Chart.ChartType.Line;
