[gradsusr] convert world coordinate distance to real distance (km)

Sat Nov 5 02:35:06 EDT 2016

Dear Mr. Jeff

Thank you very much for your advice.
I have tried it for several times, but it does not work.
I am very sorry for asking you again.

I got an error as below
Data Request Warning:  Request is completely outside file limits
Cannot contour grid - all undefined values
Error in xcbar.gs: No shading information

Here my ctl file and gs file

try.ctl

DSET
/TAKAYASU/wendi/xband/G000.grads/KINKI/20150808_0900-1700/data/KINKI00001-20150808-1400-G000-EL000000.bin
UNDEF -999

TDEF   120 LINEAR 09:00Z14JUL1500 60yr

#   'set mproj off'

   'set lat 34 34.5'
   'd  rr'
   'xcbar  8.6 8.8 0.8 4 -fw 0.11 -fh 0.15 -edge triangle -fstep 1 -line on

   'set strsiz 0.15 0.15'
   'draw string 8.5 4.15 mm'

#   'set xaxis 0 10 1'
#   'set yaxis 0 10 1'

   'close 1'

Thank you very much.
Best regards,
wendi
