| 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.                                                                                                                                                                                       |
| barsAgo      | The bar the object will be drawn at. A value of 10 would be 10 bars ago.                                                                                                                                                                                  |
| time         | The time the object will be drawn at.                                                                                                                                                                                                                     |
| y            | The y value.                                                                                                                                                                                                                                              |
| 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).                                                                                 |
