I am trying to plot the proyections of a 3D data set on its corresponding xy, zy, zx planes, but I have found no information about that. It seems it is a forbidden topic or just impossible to do. I attach a picture as example . I would like to let a data file but there is no way to upload anything here. Therefore, I paste it below if you want to try (this is ridiculous, who manages this website?). First col. is frequency, 2nd is real part and 3rd imaginary part; I recommend plotting with 1:2:3.
