How to plot XRD data as 3D plot?

I have a series of XRD diffractograms from a single sample, at different depths. I want to plot the spectra as a 3D line plot, as seen as below:
(From https://link.springer.com/article/10.1016%2FS1672-6529%2806%2960003-6)
I use the following code to view my XRD data in Matlab:
data = importdata('example_data.dat') ; % load the data from text file
semilogy(data(:,1),data(:,2)) ; % plot the data
How do I go from here?
TIA

When I click on the link, I get a ‘DOI Not Found’ error. (EDIT — The new link is to an article behind a paywall, so I do not have access to it.)
That problem aside, if the data are in a matrix, it is likely possible just use surf to plot the matrix. The axis tick labels might need to be added manually in separate statements, however this is not difficult.
If you want to upload / attach the .XRD file, it would be necessary to put it into a .zip file first. Any information you have on its contents and format would be helpful, since I dioubt many here are familiar with that format (I am not, since .dat files can contain anything).
The complete matrix, with the values imported and plotted —
Uz = unzip('Plot3D[1].zip')
x = readmatrix(Uz{1}, 'Range','A:A')
ymtx = NaN(numel(x),numel(Uz));
for k = 1:numel(Uz)
ymtx(:,k) = readmatrix(Uz{k}, 'Range','B:B');
end
ymtx
figure
surf(ymtx, 'EdgeColor','none')
grid on
xticklabels = string(x);
yt = yticks;
NrYticks = 9; % Choose Any Integer Divisor of '54'
set(gca, 'YTick',linspace(min(yt), max(yt), NrYticks), 'YTickLabel',linspace(0, -54, NrYticks))
xlabel('x')
ylabel('y')
zlabel('z')
view(60,30)
% shading('interp')
Experiment to get different results.

As always, my pleasure!
If you have further questions and have problems figuring out how the code works, don’t struggle longer than necessary. Just ask, and I’ll do my best to provide an appropriate solution (or explain the reason a solution isn’t possible).
