Stacked Line Chart
The stacked line chart is a type of chart that displays multiple line series stacked on top of each other, with the values of each series combined to show a cumulative value of the data points.
To render a stacked line chart, create an instance of the StackingLineSeries and add it to the Series collection property of the SfCartesianChart.
NOTE
The Cartesian chart has a Series as its default content.

Dashed Stacked Line
The StrokeDashArray property of StackingLineSeries is used to render the stacked line series with dashes. Odd value is considered as rendering size and even value is considered as gap.

Enable Marker
A marker, also known as a symbol, is used to determine or highlight the position of the data point. To enable markers in the series, set the ShowMarkers property to true
.

<chart:StackingLineSeries ItemsSource="{Binding Data1}"
XBindingPath="Month"
YBindingPath="Value"
ShowMarkers="True"/>
<chart:StackingLineSeries ItemsSource="{Binding Data2}"

ShowMarkers="True"/>
<chart:StackingLineSeries ItemsSource="{Binding Data3}"

YBindingPath="Value"

Marker customization
In order to change the series markers appearance, create an instance of the MarkerSettings property. The following properties are used to customize marker appearance.
-
Type, of type
ShapeType
, describes the shape of the series marker. The default value of this property is ShapeType.Circle. -
Stroke, of type
Brush
, indicates the brush used to paint the marker border. -
StrokeWidth, of type
double
, indicates the width of the marker border. -
Fill, of type
Brush
, indicates the color of the marker. -
Width, of type
double
, indicates the width of the marker. -
Height, of type
double
, indicates the height of the marker.
