I am runny a loop over set of function and in the end I want some graphs of different data. there are three variables let say a, b and c.I have generated a graph using:
plot(iteration,a,iteration,b,iteration,c)
plot(a,b)
bt it is giving the 2nd one only. I want another graph of A on x axis and C on y axis likewise C on x axis and b on y axis. I cant figure out how to get multiple plots because it is generating plot of last command only. I tried

Do not use figure() as a variable name.
fig1 = figure(1);
ax1 = axes('Parent', fig1);
h = plot(ax1, Iteration, total_util*100, 'b', Iteration, DD, 'r', Iteration, PP, 'g');
legend(h, 'total_util','d_quantity','Price');
fig2 = figure(2);
ax2 = axes('Parent', fig2);
h = plot(ax2, total_util);
The simple version of that is
figure(1);
plot(Iteration, total_util*100, 'b', Iteration, DD, 'r', Iteration, PP, 'g');
legend('total_util','d_quantity','Price');
figure(2);
plot(total_util);
but I recommend using the longer version: with the shorter version, graphics can end up going places you do not want in some cases. See https://www.mathworks.com/matlabcentral/answers/?term=tag%3Aalways-parent

You need to use hold on after the first plot and hold off after the last plot if you want multiple plots in the same figure. Use figure before all of the plots to put them in a new figure.

this is not working because both plots are showing on the same graph I want 2 different graph windows

- "hold on" if you want the graphs on the same axes
- subplot() if you want the graphs on different axes in the same figure
- figure() if you want to create different windows

If figure(1) is giving an indexing error, then you somehow have accidentally created an empty variable named figure
which figure

I have written this after the loop end.. and no other FIGURE word used
figure(1)=plot(Iteration,total_util*100,'b',Iteration,DD,'r',Iteration,PP,'g');
legend('total_util','d_quantity','Price')
figure(2)=plot(total_util);

Error
Unable to perform assignment
because the left and right sides
have a different number of
elements.
figure(1)=plot(Iteration,total_util*100,'b',Iteration,DD,'r',Iteration,PP,'g');
