# Displaying Contours and Zones On the Ceiling or Floor

## Content



The contours and zones determined for the chart can be displayed on the ceiling or the floor of the PlotCube. To do this, set the [IsContoured](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DContour.IsContoured.html) and/or the [IsZoned](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DContour.IsZoned.html) property for the ceiling or the floor.

For example, the following statement projects zones onto the ceiling of the PlotCube:

DOC-DETAILS-TAG-OPEN

DOC-SUMMARY-TAG-OPEN

To write code in Visual Basic

DOC-SUMMARY-TAG-CLOSE

```vbnet
C1Chart3D1.ChartArea.View.Ceiling.IsZoned = True
```

DOC-DETAILS-TAG-CLOSE

DOC-DETAILS-TAG-OPEN

DOC-SUMMARY-TAG-OPEN

To write code in C#

DOC-SUMMARY-TAG-CLOSE

```csharp
C1Chart3D1.ChartArea.View.Ceiling.IsZoned = true;
```

DOC-DETAILS-TAG-CLOSE

The [Chart3DContour](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DContour.html) object defined for that chart group sets the contour and zone settings used in these projections.

Contour and zone projection are ignored in two-dimensional charts, Scatter, and Bar charts.
