## Definition

```csharp
public class Polyline : Shape
```

## Examples

C#:

```csharp
using cAlgo.API;

namespace cAlgo
{
    // This sample shows how to use Polyline to draw connected lines
    public partial class PolylineSample : Indicator
    {
        protected override void Initialize()
        {
            Chart.AddControl(new Polyline
            {
                HorizontalAlignment = HorizontalAlignment.Center,
                VerticalAlignment = VerticalAlignment.Center,
                StrokeColor = Color.Red,
                StrokeThickness = 1,
                Points = new[]
                {
                    new Point(10, 10),
                    new Point(100,200),
                    new Point(10, 100),
                    new Point(10, 10),
                }
            });
        }

        public override void Calculate(int index)
        {
        }
    }
}
```

Python:

```python
import clr
clr.AddReference("cAlgo.API")

from cAlgo.API import *

class Test():
    def initialize(self):
        polyline = Polyline()
        polyline.HorizontalAlignment = HorizontalAlignment.Center
        polyline.VerticalAlignment = VerticalAlignment.Center
        polyline.StrokeColor = Color.Red
        polyline.StrokeThickness = 1
        polyline.Points = [Point(10, 10), Point(100,200), Point(10, 100), Point(10, 10)]
        api.Chart.AddControl(polyline)
```
