[gradsusr] Need help with histogram plot

[Eric Aligo]

Hi,
I would like to generate a histogram plot with precip 5 precip bins 
along the x-axis.   Below I sum up the points with precip between .01 
and 0.1" (the first bin)  summ over t=1 and t=2.  A similar calculation 
would be done for the remaining 4 precip bins.  I tried plotting this 
one bar and I get nothing.  What am I doing wrong and what's the best 
way to resolve this?

Eric


'set t 1 2'
'set lat 33.66 37.02'
'set lon -101.54 -94.36'
'pin=apcpsfc/25.4'
'bin1=const(const(maskout(maskout(pin,pin-0.0099),0.1-pin),1),0,-u)'
'summ=asumg(bin1,lon=-101.54,lon=-94.36,lat=33.66,lat=37.02)'

'set gxout bar'

'set x 1'
'set y 1'
'set z 1'

'd sum(summ,t=1,t=2)'
