[gradsusr] Problems with plotting

[Jose Augusto Paixão Veiga]

Dear users of GrAds,

I am facing problems to plot rainfall data extracted from CPC source.

As I use fortran programs to deal with some specific calculations sometimes
I need to extract data from some source and record it in a bin file to be
read in my fortran programs.

This time, after I'd selected rainfall data from a CPC ctl I get some
problems to visualise the data. The figure is attached. I believe I have to
include some specific option in OPTIONS of my CTL.

Helps and suggestions will be very appreciative.

Thanks

My CTL file is:

*dset prec-cpc-1980-2000.bin*
*title global daily analysis (grid box mean, the grid shown is the center
of the grid box)*
*options little_endian*
*undef -999.0*
*xdef   720 linear  0.25  0.50*
*ydef   360 linear  -89.75  0.50*
*zdef 1 linear  1 1*
*tdef 12 linear 01jan1979 1dy*
*vars 1*
*rain  1  00 the grid analysis (0.1mm/day)*
*ENDVARS*

The original CTL were I had extracted the data is:

*dset %y4/PRCP_CU_GAUGE_V1.0GLB_0.50deg.lnx.%y4%m2%d2*
*title global daily analysis (grid box mean, the grid shown is the center
of the grid box)*
*options  little_endian template*
*undef -999.0*
*xdef   720 linear  0.25  0.50*
*ydef   360 linear  -89.75  0.50*
*zdef 1 linear  1 1*
*tdef 12419 linear 01jan1979 1dy*
*vars 2*
*rain  1  00 the grid analysis (0.1mm/day)*
*gnum  1  00 the number of stn*
*ENDVARS*
