## 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.                                                                                                                                                               |
| y                  | The y value.                                                                                                                                                                                                                                              |
| brush              | The brush used to color draw object ([reference](/developer/desktop-sdk/references/common/drawing/brushes)).                                                                                                                                              |
| dashStyle          | Possible values include:<br />**DashStyleHelper.Dash**,<br />**DashStyleHelper.DashDot**,<br />**DashStyleHelper.DashDotDot**,<br />**DashStyleHelper.Dot**,<br />**DashStyleHelper.Solid**.                                                              |
| width              | The width of the draw object.                                                                                                                                                                                                                             |
| isDrawOnPricePanel | 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).                                                                                 |

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 horizontal line
Draw.HorizontalLine(this, "tag1", 1000, Brushes.Black);
```
