[ncl-talk] Problem creating pie-chart

[juhee yi]

Hi everyone,

I'm trying to create a pie-chart, but getting the following error message:

-- error message
----------------------------------------------------------------------------

fatal:fspan: number of elements parameter is less-than-or-equal-to one,
can't continue

fatal:["Execute.c":8575]:Execute: Error occurred at or near line 4026 in
file $NCARG_ROOT/lib/ncarg/nclscripts/csm/shea_util.ncl


fatal:["Execute.c":8575]:Execute: Error occurred at or near line 43 in file
2_2.ncl

------------------------------------------------------------------------------------------------------

I think, this error occurred because of percent value less then 0.5

Below is my script
-- coding
