MATLAB: Plot and legend for two loops

for looplegendMATLABplot

I find how to make legend for one loop. But in my Case I have two loops.
I have data writen like that:
dataM(counterNetDefsave).PIvectorM{countersave} = PIvectorM;
counterNetDefsave is changing, and countersave is changing.
for counterNetDefsave = 1:length(HidLayCyclesIn:HidLayCyclesOut);
     for countersave = 1:cycles;
        dataM(counterNetDefsave).PIvectorM{countersave} = PIvectorM;
     end
end
So what I want is … for every countersave in every counterNetDefsave, like to have a plot and legend description for every line. Now I have plot like that:
plot(dataM(1,counterNetDefsave).PIvectorM{1,countersave}),'Color';clr(countersave,:);
Please help for all plots and legend to come together in one figure

IIUC, you want to plot each column in the PIvectorM array...
Just use the vector form for input to plot
N=length(HidLayCyclesIn:HidLayCyclesOut);  % length of x 
plot([1:N]',dataM)
Then you can use legend with a cell array of labels of your choosing and they'll all match up automagically
