Hi gdkevin,

In a CoutourLayer, the z = 0 is represent as a coutour line. So I assume you would like to have a white contour line at z = 0. This can be achieved using:

//layer = ContourLayer object
//the z = 0 contour line is set to white
layer->colorAxis()->addMark(0, 0xffffff);

Hope this can help.

Regards
Peter Kwan
