How to run a generated plot function after editing a plot?

Hi! :)

When I run the function colorcode_surf_plotting, I make three variables x, y, z. Then I do some changes to my plot and save the file by generating the code.

When I so try to run the generated code after I have saved the file , then I just send three inputs, x, y, z as I thought were required to run the function I generated after I edited my plot. But it seems it is not enough.. why? I get this error message:

'index exceeds the nr of array elements'

when i try to run the code, see below, no error is shown... when do you obtain the error?

osmotisk_data = readtable("https://nl.mathworks.com/matlabcentral/answers/uploaded_files/1096510/tester_tabeller.xlsx");

x = osmotisk_data{:,1};
y = osmotisk_data{:,2};
z = osmotisk_data{:,3};

numPoints = size(z, 1);
% Make a colormap with, say, 256 potential colors .
numColors = 256 ;
cmap = jet(numColors);
% Get the rows of the colormap that each value of z should take on .
colorIndex = round(rescale(z, 1, numColors ));
for k = 1 : numPoints
    thisColor = cmap(colorIndex(k ), :);
    plot3(x(k), y(k), z(k),'.', 'Color', thisColor, 'MarkerSize', 40 )
    hold on ;
end
colormap(cmap );
colorbar
fontSize = 12 ;
xlabel('Osmotisk trykk', 'FontSize',fontSize );
ylabel('Sone nummer', 'FontSize',fontSize );
zlabel('Samlet aktivitet', 'FontSize',fontSize );
