Represents the Gann Box chart object.

C#:

```csharp
using cAlgo.API;

namespace cAlgo
{

    public partial class GannBoxSample : Indicator
    {
        protected override void Initialize()
        {
            Chart.DrawGannBox("GannBox", Chart.FirstVisibleBarIndex, Bars.ClosePrices[Chart.FirstVisibleBarIndex], Chart.LastVisibleBarIndex, Bars.ClosePrices[Chart.LastVisibleBarIndex], Color.Blue);
        }

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

Python:

```python
gannBox = api.Chart.DrawGannBox("GannBox", api.Chart.FirstVisibleBarIndex, api.Bars.ClosePrices[api.Chart.FirstVisibleBarIndex], api.Chart.LastVisibleBarIndex, api.Bars.ClosePrices[api.Chart.LastVisibleBarIndex], Color.Blue)
gannBox.IsInteractive = True
```
