plot figures using a for loop and subplot function

I have a dataset of around 180 columns of data to be plotted with respect to another constant dataset. My initial try was to plot the datasets using a for loop for different combinations of the data using a looping command and subplot function. I have succeeded in plotting for around 15-20 but then i noticed that the loop command cannot be fixed at the next index for the next set of plots.

for i = 1:15
  
    subplot (5,3,i) 
    plot (outdoor_temp,D(:,i), "r *") 
    xlabel ('Outdoor tempe(C)')
    ylabel ('Energy load')
    title (var{i})
    
end
for i = 16:30
    
    subplot (5,3,i) 
    plot (outdoor_temp,D(:,i), "r *") 
    xlabel ('Outdoor tempe(C)')
    ylabel ('Energy load')
    title (var{i})
    
end

If you want in two different figure:

figure(1)
for i = 1:15  
    subplot (5,3,i) 
    plot (outdoor_temp,D(:,i), "r *") 
    xlabel ('Outdoor tempe(C)')
    ylabel ('Energy load')
    title (var{i})    
end
figure(2)
for i = 16:30    
    subplot (5,3,i-15)   % <---- subtract 15 here 
    plot (outdoor_temp,D(:,i), "r *") 
    xlabel ('Outdoor tempe(C)')
    ylabel ('Energy load')
    title (var{i})    
end
