I'm trying to plot graph of relations of (j,s) in this for script.
s=0;
for j=1:1:10
s=s+j;
disp(['j = ', num2str(j)] );
disp(['s = ', num2str(s)] );
plot(j,s)
end
however, nothing appears when I try to plot it. What's the problem with it? And how can I plot graph of the relationship between (j,s)?

Ran in:
s=0;
hold on
for j=1:1:10
s=s+j;
disp(['j = ', num2str(j)] );
disp(['s = ', num2str(s)] );
plot(j,s,'b o')
end
j = 1
s = 1
j = 2
s = 3
j = 3
s = 6
j = 4
s = 10
j = 5
s = 15
j = 6
s = 21
j = 7
s = 28
j = 8
s = 36
j = 9
s = 45
j = 10
s = 55
hold off

Ran in:
It's more common to compute all values for s in advance and make the plot afterwards:
x = 1:10;
s = cumsum(x);
plot(x,s,'b o')
