series of subplots

[Ben Bauer]

When I do the following, the frist plot "a.gif" is fine, but b.gif is
empty or contains 1 graph only. (gnuplot: Linux version 3.7 and
octave: 2.0.17 or 2.1.9).  Am I abusing subplot, or just forgetting
to clear/close something?

a=[randn(20,1), randn(20,1), randn(20,1)]
gset term gif small size 320,720;
gset output "a.gif"
subplot(3,1,1);
title("one-a")
hist(a(1:20,1))
subplot(3,1,2);
title("two-a")
hist(a(1:20,2))
subplot(3,1,3);
title("three-a")
hist(a(1:20,3))
closeplot
 
b=[randn(20,1), randn(20,1), randn(20,1)]
gset term gif small size 320,720;
gset output "b.gif"
subplot(3,1,1);
title("one-b")
hist(b(1:20,1))
subplot(3,1,2);
title("two-b")
hist(b(1:20,2))
subplot(3,1,3);
title("three-b")
hist(b(1:20,3))
closeplot
