Chart Line Style

You can create a line style with special options such as open and end arrows for the line chart with the LineBorder property and the EnhancedSolidLine class. You can also specify line style options such as dash, cap type, and so on.

Line style containing arrows

Using Code

  1. Create a line chart.

  2. Create an EnhancedSolidLine object.

  3. Set the LineBorder property.

Example

This example code creates a line chart with a line style that contains arrows.

FarPoint.Win.Chart.EnhancedSolidLine eh = new FarPoint.Win.Chart.EnhancedSolidLine(System.Drawing.Color.Green, 1, FarPoint.Win.Chart.CompoundType.Double, FarPoint.Win.Chart.DashType.Dash, FarPoint.Win.Chart.CapType.Flat, FarPoint.Win.Chart.JoinType.Round, FarPoint.Win.Chart.ArrowType.Arrow, FarPoint.Win.Chart.ArrowType.OpenArrow, 1, 2);
FarPoint.Win.Chart.LineSeries series1 = new FarPoint.Win.Chart.LineSeries();
series1.PointMarker = new FarPoint.Win.Chart.BuiltinMarker(FarPoint.Win.Chart.MarkerShape.Circle, 7.0f);
series1.PointFill = new FarPoint.Win.Chart.GradientFill(System.Drawing.Color.Coral, System.Drawing.Color.Crimson);
