public Boolean Stairs {get; set;}
Remarks
This boolean property controls the drawing of FastLine series.
In most normal situations, a series draws a line between each Line point.
This makes the Line appear as a "mountain" shape.
However, setting Stairs to true will make the Series to draw 2 Lines between each pair of points, thus giving a "stairs" appearance.
This is most used in some financial Chart representations.
When Stairs is set to true you may set InvertedStairs to true to alter the direction of the step.
Example
[C#]
fastLine1.Stairs = true;
fastLine1.InvertedStairs =! fastLine1.InvertedStairs;
