Scatter Line of Chart for WinForms C# Tutorial

The Scatter Line Series are able to plot the data that determine a line against two linear axes. The XValue and YValue control each point of a line in the chart. The XValue is to control the horizontal axis of the point of a line and the YValue is to control the vertical axis of the point of a line respectively. The Scatter Line chart type is really similar with the mathematical Cartesian coordinate system.

How to Create Chart with Lines in C#


ScatterLineSeries scatterSeries = new ScatterLineSeries();
scatterSeries.DataPoints.Add(new ScatterDataPoint(9, 13));
scatterSeries.DataPoints.Add(new ScatterDataPoint(9, 5));
scatterSeries.DataPoints.Add(new ScatterDataPoint(7, 8));
scatterSeries.DataPoints.Add(new ScatterDataPoint(5, 4));
scatterSeries.DataPoints.Add(new ScatterDataPoint(10, 4));
scatterSeries.PointSize = new SizeF(8, 8);
this.chart1.Series.Add(scatterSeries);

ScatterLineSeries scatterSeries2 = new ScatterLineSeries();
scatterSeries2.DataPoints.Add(new ScatterDataPoint(6, 12));
scatterSeries2.DataPoints.Add(new ScatterDataPoint(10, 18));
scatterSeries2.DataPoints.Add(new ScatterDataPoint(8, 5));
scatterSeries2.DataPoints.Add(new ScatterDataPoint(9, 11));
scatterSeries2.DataPoints.Add(new ScatterDataPoint(10, 15));
scatterSeries2.Shape = new RoundRectShape(1);
scatterSeries2.PointSize = new SizeF(8, 8);
this.chart1.Series.Add(scatterSeries2);

Properties of the Scatter Line Series

Scatter Line Series is the descendent property of Scatter Series and inherit all key properties
Spline, an additional Boolean property used to draw straight lines of smooth curves
SplineTension, the property is used for setting the tension of the spline. The value of Spline should be true when customizing the SplineTension property. The below C# Code shows how to customize the Spline Tension.


scatterSeries.Spline = true;
scatterSeries.SplineTension = 0.6f;
