<b>proc defineunits</b> may be used to explicitly
39
set a certain type of scaling unit (such as date or time)
40
for an axis.<tt> </tt>
41
Usually <b>proc areadef</b> takes care of this; however
42
<b>proc defineunits</b> may be needed in situations where
43
<b>proc tabulate</b> or <b>proc autoscale</b>
44
are to be invoked before <b>proc areadef</b>, or to
45
change scaling without setting up a new area.<tt> </tt>
