multiple plots

[Victor Hanby]

I've been using 2.1.72 for about six months on MacOs 10.3.9 (octave, 
gnuplot and aquaterm binaries downloaded from hpc) and have just 
started experimenting with plots. When I run the following script for 
two multiple plots the first plot appears OK but the second plot has 
the first on superimposed on it. I've tried inserting various commands 
to no avail - any help appreciated.

A=[6 6.5 7 7.5 8 8.5 9 9.5 10];
tret=[59 53.97 49.6 45.74 42.31 39.25 36.48 33.98 31.7];
mdot=[0.597 0.325 0.233 0.1863 0.158 0.139 0.126 0.116 0.108];

subplot(2,1,1)
xlabel("radiator area (m^2)")
ylabel("return water temperature (C)")
plot(A,tret)

subplot(2,1,2)
xlabel("radiator area (m^2)")
ylabel("water mass flow rate (kg/s)")
plot(A,mdot)
