[wxqc] Bar quality graphs

[Al Huggard]

To any one who can help me.  On the QC graph for my station C3525, I am
tracking right (above and below) on the analysis track. However on the "all
stations" graph I am still about 1mb low of the target box.  If I include
the surrounding airports on the graph of just my station I appear to be
about 1mb high as does the analysis track. Should I adjust for the target
box on the "all stations" graph (increase my bar by 1mb or should I reduce
my bar by .5 or l mb to more closely follow the surrounding measurements on
the airport stations which I presume to be the most accurate.  I am about +
or - 30 miles south and southwest of the airport stations. I haven't had a
calm enough wind day recently to check my local Airport although it is a
very  small privately operated station and for precise accuracy they might
be suspect.
