plotting 4 variables in same graph

i have four variables

h=[0.01 0.02 0.04 0.06 0.09 0.17 0.29 0.51 0.67 0.84];
sa=[31.85 31.84 31.81 31.79 31.76 31.68  31.56 31.35  31.18 31.01];
a=[68.14 68.14 68.14 68.14 68.14 68.14 68.14 68.14 68.14 68.14];
sd=[-3.80 -3.70 -3.60 -3.50 -3.40 -3.30 -3.20 -3.10 -3.00 -2.90];

i want to plot them in single graph. "h","sa", and "a" are dependent on "sd". also want to see any relationship of all variables with "sd"

Answer 1

plot(sd,[h;sa;a].')
legend('H','SA','A')
xlabel('SD')

Finish 'salt to suit'...

You've only got one independent variable with three dependent ones???
