[gradsusr] Color bar

[RafaelCB]

sorry ... do so with the wind...
Example:
'set gxout shaded'
'set ccols 0 92 94 97 61 64 69'
'set clevs 5 10 15 20 30 40'
'd mag(u10,v10)'
'set gxout contour'
'set ccolor 1'
'set clevs 5 10 15 20 30 40'
'd mag(u10,v10)'
'run /home/meteop/rafael/reanalysis/cbarn_new.gs 0.7 0.0'
'set gxout barb'
'set arrlab off'
'set arrscl 0.5 25'
'set ccolor 1'
'd skip(u10,7);skip(v10,7);mag(u10,v10)'
'run /home/meteop/rafael/reanalysis/cbarn_new.gs 0.7 1.0'
