示例1: Render
public override void Render(IRenderContext rc, PlotModel model)
{
// transform to screen coordinates
var p0 = this.Transform(this.StartPoint);
var p1 = this.Transform(this.EndPoint);
var direction = p1 - p0;
var normal = new ScreenVector(direction.Y, -direction.X);
// the end points of the arrow head, scaled by length of arrow
var p2 = p1 - (direction * 0.2) + (normal * 0.1);
var p3 = p1 - (direction * 0.2) - (normal * 0.1);
// draw the line segments
rc.DrawLineSegments(new[] { p0, p1, p1, p2, p1, p3 }, this.ActualColor, this.StrokeThickness);
