3D image from a stack of 2D images

Dear all,

I would like to prepare an image such as presented in the attached figure. I have a stack of 2D images of the (E, k_y) direction obtained at different k_x.

I have tried to use the 3D editor but all I got was an unscaled (1,1) representation which did not reflect the scaling of the images.

Please also explain how this "window" in the image could be achieved.

Thank you very much for your help!

Best
Patrick
