I'm trying to set the scatter3 plot markers' colors based on the maximum range of z variables, using clim. No matter what I do, all markers always plot in the default color.

Tz = readtable("data.xlsx","Sheet","z");
[m,n] = size(Tz);
[Tzmin, Tzminidx] = min(Tz{:,2:n}); % the first column needs to be discarded for some reason
[Tzmax, Tzmaxidx] = max(Tz{:,2:n});
r = 75; % this will later change in a loop, thus I want the color range to be fixed
x = readtable("data.xlsx","Sheet","x");
x = table2array(x(r,2:n));
y = readtable("data.xlsx","Sheet","y");
y = table2array(y(r,2:n));
z = readtable("data.xlsx","Sheet","z");
z = table2array(z(r,2:n));
% all three sheets are of the same size m x n
scatter3(x, y, z, 'filled', 'MarkerEdgeColor', 'none');
set(gca,'clim',[Tzmin(1) Tzmax(n-1)]); % I want to fix this range based on the min and max values of z
view(-45,45);
colorbar();

The result is always:

Note, I'm always getting the default coloring, even without using clim. That is, even if I specify any colorbar, etc. I always get the default marker color.

What am I doing wrong? Thanks.
