Stacked Line 100

The stacked line 100 chart is a type of chart that displays multiple line series stacked on top of each other, to indicate the cumulative value of the data points at 100%.

To render a stacked line 100 chart, create an instance of the StackingLine100Series and add it to the Series collection property of the SfCartesianChart.

NOTE

The Cartesian chart has a Series as its default content.

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.
