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 ....

EXIST_PLOT_3D is used by PageBase::GetType

PageBase pb;
pb = Project.Pages();
if( pb.GetType() == EXIST_PLOT_3D )
printf("%s is a 3D plot.\n",pb.GetName());

Is it possible to have a multi-layer graph page with a mixture of 2D and 3D plots? That might be a problem here.

Using Mike Buess's test code, I find that the pb.GetType() call returns EXIST_PLOT with all types of GraphPages. The value returned by pb.GetType() did not depend upon the type of GraphLayer (i.e. whether 2D or 3D) or combination of GraphLayers present on the GraphPage.

Until we provide a solution to this in Origin 8, use the following for now,

 
void test()
{
	GraphLayer gl = Project.ActiveLayer();
	if(gl)
	{
		Tree tr;
		bool bIsXYZ = true;
		try {
			tr = gl.ZAxis.Scale;
		}
		catch(int nErr)
		{
			bIsXYZ = false;
		}
		if(bIsXYZ)
			out_str("Is XYZ layer");
		else
			out_str("No Z axis found");
	}
}
