Confusion with labels and viewports
Suppose I have a plot that I'd like the labels I create (via 'LABEL'
command) to always be in the same place regardless of whether I change
the aspect ratio, or the viewport, or things like that. 'LABEL/NOUSER'
is too rigid for this purpose, since I usually end up with labels drawn
outside the plot itself, or in the middle, or somewhere else wrong.
So, using 'SHOW SYMBOLS/ALL', I see a number of variables I could use,
including
PPL$XMIN1, PPL$XMAX1, PPL$YMIN1, PPL$YMAX1,
XAXIS_MIN, XAXIS_MAX, YAXIS_MIN, and $AXIS_MAX
The *AXIS_M* ones make sense - for the time series data I'm plotting,
with a fixed vertical range (i.e., 'PLOT/VL=0:10:1'), the YAXIS values
are right what they should be. The XAXIS values are basically in the
units of the time axis, for example, since my time axis is specified as
'days since 1979-01-01', XAXIS_MIN has a value of 722517, when divided
by 365, is ~1979. This also makes sense.
However, the PPL$ values make no sense to me at all. In this example,
PPL$XMIN1 is 5.6928E+04, PPL$XMAX1 is 1.1169E+06. What "units" are
those?
I can experiment around with manipulating the X and Y positions of my
LABELs, until they miraculously end up where I want them, but that is
too trial-and-error to be efficient.
Ideas would be most welcome.
