# ChartShape (interface)

Represents the Shape chart object. Allows drawing a Rectangle, a Triangle, and an Ellipse on the chart.

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

- CLI: Created and kept with all its properties, but never drawn: the CLI displays no chart.
- Cloud: Created and kept with all its properties, but never drawn: the cloud displays no chart.

## Definition

```csharp
public interface ChartShape
```

## Examples

C#:

```csharp
ChartShape shape = Chart.DrawRectangle("zone", Bars.OpenTimes.Last(20), Bars.LowPrices.Last(20), Bars.OpenTimes.LastValue, Bars.HighPrices.LastValue, Color.FromArgb(60, Color.Blue));
shape.IsFilled = true;
shape.LineStyle = LineStyle.Dots;
Print("Shape: {0} | Filled: {1}", shape.Name, shape.IsFilled);
```

Python:

```python
shape = api.Chart.DrawRectangle("zone", api.Bars.OpenTimes.Last(20), api.Bars.LowPrices.Last(20), api.Bars.OpenTimes.LastValue, api.Bars.HighPrices.LastValue, Color.FromArgb(60, Color.Blue))
shape.IsFilled = True
shape.LineStyle = LineStyle.Dots
api.Print(f"Shape: {shape.Name} | Filled: {shape.IsFilled}")
```
