Drawing a horizontal line with an AnnotationArrow?


Recommended Posts

I'm currently using ChartFX 7, version 7.0.2281.32010.

I'm attempting to draw a short horizontal line segment with an AnnotationArrow object.  Using this code:

AnnotationArrow objectiveLine = new AnnotationArrow();

objectiveLine.AllowModify = false;

objectiveLine.AllowMove = false;

if (index != 3)

  objectiveLine.Border.Style = DashStyle.Dash;

objectiveLine.Border.Color = OBJECTIVE_LINE_COLOR;

objectiveLine.EndCap.Height = 0;

objectiveLine.EndCap.Width = 0;

objectiveLine.Height = 1;

objectiveLine.Width = (chart.ChartAreaRectangle.Width - chart.PlotAreaMargin.Left - chart.PlotAreaMargin.Right) / 4;

objectiveLine.Attach(index + 1, objective);


...I get the lines I need, but they're not quite horizontal.  Is there any way to get this to work?

Please try the following code:

AnnotationArrow arrow = new AnnotationArrow();arrow.Border.Color = Color.Red;arrow.Border.Width = 4;arrow.Color = Color.Red;arrow.Height = 0;arrow.Width = 100;arrow.Attach(2, 30);arrow.EndCap.Height = 1;arrow.EndCap.Width = 0;arrow.EndCap.Filled = false;
