Add legend to for loop

I am trying to add legend to for loop and I need my legend to have variables used to plot graphs.

fig1 = figure()
ax1 =axes('Parent',fig1)
    
 for  C  = 1:36
       
           for    I = [1:5]
%Cl Vs Alpha

   
        index = 1;
        XVAR = 'Alpha';
        YVAR='CL';
        MACH = 0.27;
        ALTITUDE = 0;
         legend(sprintf('TEST_AERO%d_%d',I , C))     
        hold on
        TEST_AERO_FINAL.(sprintf('TEST_AERO%d_%d',I , C)).DES_SPACE{index}.plot(XVAR,YVAR,MACH,ALTITUDE,ax1)

  end
 end

Generally, it's best if you specify the plot object handle when you call legend(). Since all of your plotting code is missing, consider the simplified example:

numberofplots=3;

h=zeros(numberofplots,1); % preallocate handles vector
legendstrings=cell(numberofplots,1); % preallocate legend strings
for n=1:numberofplots
    x=rand(10,1); % garbage example data
    y=rand(10,1);
    
    h(n)=plot(x,y); hold on; % store this plot handle
    legendstrings{n}=sprintf('X1 = %f',x(1)); % store this legend string
end
% the call to legend() doesn't need to be in the loop
legend(h,legendstrings,'location','northwest');
