Draws an arrow line.
Method Return Value
An IArrowLine object that represents the draw object.
Syntax
DrawArrowLine(string tag, int startBarsAgo, double startY, int endBarsAgo, double endY, Color color)
DrawArrowLine(string tag, bool autoScale, int startBarsAgo, double startY, int endBarsAgo, double endY, Color color, DashStyle dashStyle, int width)
DrawArrowLine(string tag, bool autoScale, DateTime startTime, double startY, DateTime endTime, double endY, Color color, DashStyle dashStyle, int width)
Parameters
tag
|
A user defined unique id used to reference the draw object. For example, if you pass in a value of "myTag", each time this tag is used, the same draw object is modified. If unique tags are used each time, a new draw object will be created each time.
|
autoScale
|
Determines if the draw object will be included in the y-axis scale. Default value is false.
|
startBarsAgo
|
The starting bar (x axis co-ordinate) where the draw object will be drawn. For example, a value of 10 would paint the draw object 10 bars back.
|
startTime
|
The starting time where the draw object will be drawn.
|
startY
|
The starting y value co-ordinate where the draw object will be drawn
|
endBarsAgo
|
The end bar (x axis co-ordinate) where the draw object will terminate
|
endTime
|
The end time where the draw object will terminate
|
endY
|
The end y value co-ordinate where the draw object will terminate
|
color
|
The draw object color (reference)
|
dashStyle
|
DashStyle.Dash
DashStyle.DashDot
DashStyle.DashDotDot
DashStyle.Dot
DashStyle.Solid
(reference)
Note: Drawing objects with y values very far off the visible canvas can lead to performance hits. Fancier DashStyles like DashDotDot will also require more resources than simple DashStyles like Solid.
|
width
|
The width of the draw object
|
Examples
DrawArrowLine("tag1", false, 10, 1000, 0, 1001, Color.LimeGreen, DashStyle.Dot, 2);
