SWITCH expression ERROR !!!!

I want to plot 3 graphics successively. So I use this code:

for h=1:3
switch h
case 1
semilogy(x, y, 'rx-')
case 2
semilogy(x, y, 'bo-')
case 3
semilogy(x, y, 'md-')

but it gives this message "" SWITCH expression must be a scalar or string constant."

What can I do? Thanks in advance:)
