Is there an OriginC method for determining whether an Origin Graph is Three dimensional other than something like
GraphPage gPG=Project.Pages(-1);
GraphLayer Lay=gPG.Layers(-1);
bool Flag;
if(gPG.IsValid())
{
Flag=LabTalk.Layer.Is3D;
}
//
I found the constant EXIST_PLOT_3D in the OC_const.h file but I do not know which functions(s) use it ....
