Draw.Rectangle(NinjaScriptBase owner, string tag, bool isAutoScale, int startBarsAgo, double startY, int endBarsAgo, double endY, Brush brush, Brush areaBrush, int areaOpacity)
Draw.Rectangle(NinjaScriptBase owner, string tag, bool isAutoScale, DateTime startTime, double startY, DateTime endTime, double endY, Brush brush, Brush areaBrush, int areaOpacity)
Draw.Rectangle(NinjaScriptBase owner, string tag, int startBarsAgo, double startY, int endBarsAgo, double endY, Brush brush, bool drawOnPricePanel)
Draw.Rectangle(NinjaScriptBase owner, string tag, bool isAutoScale, int startBarsAgo, double startY, int endBarsAgo, double endY, Brush brush, Brush areaBrush, int areaOpacity, bool drawOnPricePanel)
Draw.Rectangle(NinjaScriptBase owner, string tag, bool isAutoScale, DateTime startTime, double startY, DateTime endTime, double endY, Brush brush, Brush areaBrush, int areaOpacity, bool drawOnPricePanel)
Draw.Rectangle(NinjaScriptBase owner, string tag, int startBarsAgo, double startY, int endBarsAgo, double endY, bool isGlobal, string templateName)
Draw.Rectangle(NinjaScriptBase owner, string tag, DateTime startTime, double startY, DateTime endTime, double endY, bool isGlobal, string templateName)

Parameters

owner	The hosting NinjaScript object which is calling the draw method Typically will be the object which is calling the draw method (e.g., "this")
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.
isAutoScale	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
brush	The brush used to color the outline of draw object (reference)
areaBrush	The brush used to color the fill area of the draw object (reference)
areaOpacity	Sets the level of transparency for the fill color. Valid values between 0 - 100. (0 = completely transparent, 100 = no opacity)
drawOnPricePanel	Determines if the draw-object should be on the price panel or a separate panel
isGlobal	Determines if the draw object will be global across all charts which match the instrument
templateName	The name of the drawing tool template the object will use to determine various visual properties (empty string could be used to just use the UI default visuals instead)
