# ChartArea.DrawRectangle

Member of [ChartArea](https://help.ctrader.com/ctrader-algo/references/Chart/ChartArea/index.md).

## DrawRectangle(string name, DateTime time1, double y1, DateTime time2, double y2, Color color)

Draws a rectangle.

Environments: Desktop supported · CLI works differently · Cloud works differently.

- CLI: The object is created and returned, but never drawn: the CLI displays no chart.
- Cloud: The object is created and returned, but never drawn: the cloud displays no chart.

C#:

```csharp
ChartRectangle DrawRectangle(string name, DateTime time1, double y1, DateTime time2, double y2, Color color)
```

Python:

```python
chartArea.DrawRectangle(name: str, time1: DateTime, y1: float, time2: DateTime, y2: float, color: Color) -> ChartRectangle
```

### Parameters

- `name` (`string`, Python `str`): The chart object name - a unique name that can be only used once for a chart area. If duplicated, the chart object will be replaced with a new one of the same name.
- `time1` (`DateTime`, Python `DateTime`): The time value of the rectangle point 1 location on the X-axis.
- `y1` (`double`, Python `float`): The Y-axis value of the rectangle point 1 location.
- `time2` (`DateTime`, Python `DateTime`): The time value of the rectangle point 2 location on the X-axis.
- `y2` (`double`, Python `float`): The Y-axis value of the rectangle point 2 location.
- `color` (`Color`, Python `Color`): The rectangle lines color.

### Returns

`ChartRectangle` — ChartRectangle.

### Examples

C#:

```csharp
var rectangle = Chart.DrawRectangle("zone", Bars.OpenTimes.Last(20), Bars.LowPrices.Last(20), Bars.OpenTimes.LastValue, Bars.HighPrices.LastValue, Color.FromArgb(80, Color.Blue));
rectangle.IsFilled = true;
Print("Zone from {0} to {1}", rectangle.Y1, rectangle.Y2);
```

Python:

```python
rectangle = api.Chart.DrawRectangle("zone", api.Bars.OpenTimes.Last(20), api.Bars.LowPrices.Last(20), api.Bars.OpenTimes.LastValue, api.Bars.HighPrices.LastValue, Color.FromArgb(80, Color.Blue))
rectangle.IsFilled = True
api.Print(f"Zone from {rectangle.Y1} to {rectangle.Y2}")
```
