GET:PHYSICA_keywords:AUTOSCALE
ON - Autoscale the horizontal and the vertical axes
OFF - Turn off all autoscaling
COMMENSURATE - Autoscale the horizontal and vertical axes and
change the lengths of the axes to be commensurate
XAXIS - Autoscale the x-axis only
YAXIS - Autoscale the y-axis only
When the \VIRTUAL qualifier is used, the virtual minima and
maxima for the axes will be determined, so that the axes may
not begin or end at a large tic mark. If the keyword ON is used,
both x- and y-axes will have virtual minima and maxima. If the
keyword XAXIS is used, only the x-axis will have virtual minimum
and maximum. If the keyword YAXIS is used, only the y-axis will
have virtual minimum and maximum.
