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. Capture.JPG

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);
