Show more than plot at the same time

I have several variables that I want to show in graphs , and I have written the code as follows :

plot(Salinity_stage_max);
ylabel("ppm")
xlabel("Days")
title("Salinity profile")

plot(PR);
ylabel("PR")
xlabel("Days")
title("Performance Ratio profile")

plot(STEC);
hold on
ylabel("Kj/Kg")
xlabel("Days")
title("Specific thermal energy consumption")
hold off

But Matlab shows only the last command of the plot, is there a way so that all the plots appear either in separate windows or in one grouped window
