How to separate the elements of a table with their names?

Attached is the table. I need to plot rad vs k_val and total vs k_val for each individual k_name. The output would be TWO plots each have all k_names plot stacked: K10, K11, K12, K1, K2, K6 and so on.

My question is how to separate the Xs and Ys from table based on their k_name. One way is by all k_names in a for loop if the ith and ith+1 k_name are the same or not.

I wanted to check whether there is easier way so that I can avoid for loop? I dont want to separate them by their period as their frequency might alter.

I am not sure of getting rid of the for-loop. But the following code can achieve what you are looking for neatly.

Assume T is the name of the table.

k_names = unique(T.k_name);

for value = 1:length(k_names)
    h = string(T.k_name) == k_names(value);
    rad(:,value) = T.rad(h);
    k_val(:,value) = T.k_val(h);
    total(:,value) = T.total(h);        
end

plot(rad,k_val);
plot(total,k_val);

Note that this assumes that there are the same number of occurances of each name.

Yes. Thanks for pointing out.
