In my experience, to get best results it is better to bite the bullet
and just use the position parameter to plot manually. That ensures
that
the plots are positioned just the way you need them.

For instance I would do something like:

xrange=[2,7]
x=findgen(10)
y1=x^2
y2=sqrt(x)

plot,x,y1,xrange=xrange,position=[0.1,0.1,0.9,0.5]
plot,x,y2,xrange=xrange,position=[0.1,0.5,0.9,0.9],/
noerase,xtickn=replicate(' ',30)

Of course you may want to fine tune the y tick labels so they do not
collide.

Ciao,
Paolo
