No, I just tried plot_oo on IDL 4.0 on AXP/VMS and it works.
I have always thought that plot_oo, plot_io, etc. were the wrong way to do it.
All of the other axis structure elements (!X.RANGE, !X.STYLE, etc.) are
"sticky", i.e. if you set them they stay set. However, !X.TYPE is not sticky -
if you set !X.TYPE=1 (for a log axis) and then issue a plot command it sets
!X.TYPE back to zero. This lack of symmetry is a real pain.
PLOT, FINDGEN(100), XTYPE=1 ; This draws a log-lin plot
!X.TYPE=1
PLOT, FINDGEN(100) ; This draws a lin-lin plot, !X.TYPE gets reset
