The following example produces interesting results in IDL 5.2:

window,/free,xs=500,ys=800
!p.multi=[0,1,3,0,0]
!p.charsize=2.0
dx=1.0d-4
plot,[0],[0],xrange=[x0,x0+dx],yrange=[x0,x0+dx],xstyle=1,ystyle=1
dx=1.0d-3
plot,[0],[0],xrange=[x0,x0+dx],yrange=[x0,x0+dx],xstyle=1,ystyle=1
dx=1.0d-2
plot,[0],[0],xrange=[x0,x0+dx],yrange=[x0,x0+dx],xstyle=1,ystyle=1

The non-uniform tick spacing on the Y axis of the middle plot is quite
novel.

Cheers,
Liam.
