ScatterArea
ScatterAreaSeries plot their data using two numerical values. Once positioned on a plane the points are connected to form a line. Further, the area enclosed by this line and the categorical axis is filled. Below is a sample snippet that demonstrates how to set up two ScaterArea series:
Initial Setup
ScatterAreaSeries scatterSeries = new ScatterAreaSeries();
scatterSeries.DataPoints.Add(new ScatterDataPoint(15, 19));
scatterSeries.DataPoints.Add(new ScatterDataPoint(18, 10));
scatterSeries.DataPoints.Add(new ScatterDataPoint(13, 15));
scatterSeries.DataPoints.Add(new ScatterDataPoint(10, 8));
scatterSeries.DataPoints.Add(new ScatterDataPoint(5, 2));
this.radChartView1.Series.Add(scatterSeries);
ScatterAreaSeries scatterSeries2 = new ScatterAreaSeries();
scatterSeries2.DataPoints.Add(new ScatterDataPoint(2, 24));
scatterSeries2.DataPoints.Add(new ScatterDataPoint(7, 12));
scatterSeries2.DataPoints.Add(new ScatterDataPoint(15, 10));
scatterSeries2.DataPoints.Add(new ScatterDataPoint(18, 22));
scatterSeries2.DataPoints.Add(new ScatterDataPoint(19, 19));
scatterSeries2.Spline = true;
this.radChartView1.Series.Add(scatterSeries2); Figure 1: Initial Setup
Properties
The following list shows the most important properties of the ScaterAreaSeries.
-
XValueMember: If a DataSource is set, the property determines the name of the field that holds the XValue.
-
YValueMember: If a DataSource is set, the property determines the name of the field that holds the YValue.
-
Spline: Boolean property, which indicates whether the series will draw straight lines of smooth curves.
-
SplineTension: The property sets the tension of the spline. The property will have effect only if the Spline property is set to true.
-
StrokeMode: This property controls what part of the area border should be marked with line.
Set StrokeMode
scatterSeries.StrokeMode = AreaSeriesStrokeMode.Points;Figure 2: Stroke Mode
