How can I plot a previous plot into a new figure?

I have a for loop that is plotting Temperature against Fuel-Mass Percent. The temperature values are being read from text files. Each time a text file is read the previous temperature matrix is erased. I plotted the first set of Temperature values in figure 1 and the second set of Temperature values in figure 2, but now I need to plot the second set of Temperature plot with Temperature sets 3,4, and 5. How can I store the second figure and add it to my third figure which contains plots 3,4, and 5? Thank you for the help!

Well...

figure2 = 2;   %you said "figure 2" so I assume its numeric handle is 2.
figure3 = 3;   %you said "figure 3" so I assume its numeric handle is 3.

ax2 = findobj(figure2, 'type', 'axes');
ax3 = findobj(figure3, 'type', 'axes');

copyobj(get(ax2, 'Children'), ax3);

But really, easier is to just keep a copy of the data and plot() it along with the other data.
