Plotting a second graph on an existing figure

Hello,

In a specific exercise, I was meant to first show results of a function plotted on a graph, and then plot a second set of results on the previous figure. I did it using a hold on function after the code of the first plot, however, it only ended up presenting both graphs on the same figure, and not show the first graph alone and then both of them. I hope the process is clear :)

if true
  % code
%clause c: defining baseline parameters
R=22;
L = 300;
N = [1:3:45];
X = (L.*N)./(R+N);
figure; plot(N, X); xlim([1 45])
xlabel('Number of worms on plate'); ylabel('Number of eggs layed')
title('The link between worms on plate and number of eggs hatched')
hold on
%clause d: input
H = [16 40 69 87 106 131 142 147 166 161 175 180 192 198 194];
plot(N, H); legend('Number of eggs expected','Number of eggs layed');
end

You need something like this:

R=22;
L = 300;
N = [1:3:45];
X = (L.*N)./(R+N);
figure(1); 
plot(N, X); 
xlim([1 45])
xlabel('Number of worms on plate'); ylabel('Number of eggs layed')
title('The link between worms on plate and number of eggs hatched')
%clause d: input
H = [16 40 69 87 106 131 142 147 166 161 175 180 192 198 194];
figure(2);
plot(N,X,N,H);
legend('Number of eggs expected','Number of eggs layed');

ok, so technically it replotted the first graph- as it appears in two different windows.

Exactly. Also, two separate figures are defined.
