| 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. |
| 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.                                                                                                                                                                                                                     |
| brush            | The brush used to color draw object ([reference](https://msdn.microsoft.com/en-us/library/system.windows.media.brushes%28v=vs.110%29.aspx)).                                                                                                              |

| width            | The width of the draw object.                                                                                                                                                                                                                             |

| 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).                                                                                 |

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**.

## Examples

```csharp
// Draws a vertical line  
Draw.VerticalLine(this, "tag1", 10, Brushes.Black);

```
