Plotting based on a for loop from a cell array

Hi every one,

I am trying to plot acceleration data, which I always have in X, Y & Z direction.

To avoid doing everything 3 times, I have created a cell array: names = {'X', 'Y', 'Z'}.

I now want to plot this data in 3 subplots using a for loop, which yields something like this:

for i = 1:length(names)

figure();

subplot(3,1,i);

plot(UA_SEG.Acc_(names{i}));

end

In which UA_SEG is a table containing the data I'm using.

However, I am doing something wrong in accessing the cell array, as it won't plot and I get the error "Error using tabular/dotParenReference (line 69), Unrecognized variable name 'Acc_'."

Which means that it does not recognize the first element of the array as being 'X', but I am not sure which braces or indexing to use to make this work.

Thank you in advance

xyz = 'XYZ';
figure()
for k = 1:3
    subplot(3,1,k)
    plot(UA_SEG{:,['Acc',xyz(k)]})
end

Thank you Stephen!

I had looked at a lot of information pages before, but I hadn't found that one yet.
