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.

isn't there any easy way? a one line function?
