Custom axis in Gizmo Surface Plot

Hello,

I am using Gizmo to create a 3D surface plot of my temperature dependent XRD data. I have got 60 XRD patterns, each one collected at a different temperature. To present the data properly I would like to create a 3D graph that has 2theta on the x_0-axis, Temperature on the y_0-axis and intensity on the z_0-axis of my box. My data is stored in a 2D wave (each column contains intensity values of one pattern).
When I create a new surface plot I get almost exactly what I need, except for the fact that the y_0 axis is showing the number of the scan and not the temperature (see image attached). What makes sense at this point because the temperature values are not contained in the 2D wave. They are stored in a separate 1D wave and I would like to append these values to the y_0 axis. I tried using a custom axis, but for some reason I don't understand the custom axis won't show up in the plot as soon as the surface is dragged into the Display List. How can I display the custom axis AND the surface at the same time? Or is there another way to tackle the problem? Maybe via transforming my data into XYZ waves?

I am using Igor 6.37

Thanks
