We are sorry but it is not possible to provide custom contour levels in C1Chart3D as it internally calculates the contour levels based on the provided data. However, you can set the contour levels count using the C1Chart3D's ContourLevelsCount
> I read that I can use ContourData on the GridDataSeries, but I don't know what format the data should be in
property contains the contour value for corresponding ZData. For example, contour value for ZData[1, 2] will be present in Contour[1, 2].
Please refer to the same from the attached sample. (see Chart3DContour.zip)
> Also should the collection editor work for ContourData and ZData? I was unable to add any data
Since there is no editor available for 2D array and hence it won't be possible to edit the ContourData/ZData properties in designer. JFYI, CollectionEditor supports editing properties of type ICollection
