Trying to plot contourf onto hgtransform is now blank

I'm trying to do the following: https://uk.mathworks.com/matlabcentral/answers/525119-plot-contour-in-xz-and-yz-plane#comment_846566

My data works when I plot it with contourf(X,Y,z) but when I try to plot it as contourf(X, Y, z,'Parent',HG) it's just blank and I have no idea why.

I have attached the X,Y,z data. I'm trying to do exactly as it says in that comment, it's exactly what I need but my contour just seems to be blank

Actually it seems like it goes blank when I try to rotate it? i have no idea anymore

Hi,

I had found that we cannot use makehgtform in non-square matrices. So, you are not able to produce results.

HG.Matrix = makehgtform('xrotate', pi/2);

Whereas in that example he is using a square matrix to transform.

To produces results for xy, yz and zx plane. You may use contourf() function with different alignments of parameters, i.e.

load('matlab.mat');

contourf(X,Y,z); %for XY plane
contourf(Y,z,X); %for YZ plane
contourf(X,z,Y); %for Xz plane

Hope this helps!

Can I put my data in square matrix form instead by extending it? Can you provide guidance on how? i.e. making z values 0 for the rest of the matrix to make a 173x173 matrix?

Edit: I tried with z(173,114:173)=0 but I still cannot rotate it even though it is square, can you provide any advice?
