## Method Return Value

A **[RegionHighlightY](/developer/desktop-sdk/references/common/drawing/draw-regionhighlighty/regionhighlighty)** object that represents the draw object.

## Syntax

`Draw.RegionHighlightY(NinjaScriptBase owner, string tag, double startY, double endY, Brush brush)`

`Draw.RegionHighlightY(NinjaScriptBase owner, string tag, bool isAutoScale, double startY, double endY, Brush brush, Brush areaBrush, int areaOpacity)`

`Draw.RegionHighlightY(NinjaScriptBase owner, string tag, double startY, double endY, bool isGlobal, string templateName)`

## 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.                                                                                                                                                               |
| startY       | The starting y value co-ordinate where the draw object will be drawn.                                                                                                                                                                                     |
| endY         | The ending y value co-ordinate where the draw object will be drawn.                                                                                                                                                                                       |
| brush        | The brush used to color the outline of draw object ([reference](/developer/desktop-sdk/references/common/drawing/brushes)).                                                                                                                               |
| areaBrush    | The brush used to color the fill area of the draw object ([reference](/developer/desktop-sdk/references/common/drawing/brushes)).                                                                                                                         |
| areaOpacity  | Sets the level of transparency for the fill color. Valid values between 0 - 100. (0 = completely transparent, 100 = no opacity).                                                                                                                          |
| 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).                                                                                 |

## Examples

```csharp
// Fills in the region between the startY and endY
Draw.RegionHighlightY(this, "tag1", true, High[0], Low[0], Brushes.Blue, Brushes.Green, 20);
```
