3D graph data from excel file.

Hi:

I am beginning to use Diadem, I want to plot a 3D graph, the data is from an excel file, on the x channel I assigned data from simulation 1, on the y channel the data from simulation 2 and on the z channel I want the data from time stamp. when I plot the data nothing appeared in the graph, but if I assigned to the z channel the data correspond to the samples I obtain the graph. But I do not want this.

I attached the excel file.

Thanks.
