Method Return Value
An IRay object that represents the draw object.
Syntax
DrawRay(string tag, int anchor1BarsAgo, double anchor1Y, int anchor2BarsAgo, double anchor2Y, Color color)
DrawRay(string tag, bool autoScale, int anchor1BarsAgo, double anchor1Y, int anchor2BarsAgo, double anchor2Y, Color color, DashStyle dashStyle, int width)
DrawRay(string tag, bool autoScale, DateTime anchor1Time, double anchor1Y, DateTime anchor2Time, double anchor2Y, 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.
|
anchor1BarsAgo
|
The number of bars ago (x value) of the 1st anchor point
|
anchor1Time
|
The time of the 1st anchor point
|
anchor1Y
|
The y value of the 1st anchor point
|
anchor2BarsAgo
|
The number of bars ago (x value) of the 2nd anchor point
|
anchor2Time
|
The time of the 2nd anchor point
|
anchor2Y
|
The y value of the 2nd anchor point
|
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
|
