## Parameters

| Parameter                                       | Description                                                                                                                                                                                                                                                |
| ----------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 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.                                                                                                                                                                                                     |
| endBarsAgo                                      | The end bar (x axis co-ordinate) where the draw object will terminate.                                                                                                                                                                                     |
| endTime                                         | The end time where the draw object will terminate.                                                                                                                                                                                                         |
| brush                                           | The brush used to color the outline of draw object ([reference](/developer/desktop-sdk/references/common/drawing/brushes)).                                                                                                                                |
| upperDashStyle, middleDashStyle, lowerDashStyle | **DashStyleHelper.Dash**, **DashStyleHelper.DashDot**, **DashStyleHelper.DashDotDot**, **DashStyleHelper.Dot**, **DashStyleHelper.Solid**. Note: Fancier DashStyles like **DashDotDot** will require more resources than simple DashStyles like **Solid**. |
| upperBrush, middleBrush, lowerBrush             | The line colors ([reference](/developer/desktop-sdk/references/common/drawing/brushes)).                                                                                                                                                                   |
| upperWidth, middleWidth, lowerWidth             | The line width.                                                                                                                                                                                                                                            |
| 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).                                                                                  |
