# Customizing the Number of Levels

## Content



Use the [NumLevels](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DContour.NumLevels.html) property to set the number of contour levels to use. This has no effect when the chart is using a custom distribution table. You can specify up to one hundred levels. The more levels used, the finer the distribution table. **NumLevels** is located under **Contour** node in the **ChartGroup Collection Editor**. For information on how to access the **ChartGroup Collection Editor**, see [Chart3DGroup Collection Editor](/componentone/docs/win/online-chart3d/3dchartdesigntimesup/c1chart3dcollectione/chart3dgroupcollecti).
