How to plot multiple graphs in one figure ?

I have two codes. Each code has four graphs. I want to plot two graphs in one figure. For example: Dead nodes vs Round graph of two should be in one figure. In the same way other graphs also. I tried hold on function but still not getting. How to merge the two codes in order to get the graphs ?
