Re: [ferret_users] Contours and sigdig

Dear Serena,

I noticed that when I draw less than 5 levels of contour the number of digits of the contour labels is increased by one.
Here are two examples:
use coads_climatology.cdf
contour/x=50w:20e/y=30s:30n/sigdig=1/lev=(20,30,1) SST[l=@ave]
---> More than 5 contours, sigdig is OK
contour/x=50w:20e/y=30s:30n/sigdig=1/lev=(20,23,1) SST[l=@ave]
---> Less than 5 contours, the significant digits in the contour labels is not 1, but 2

Maybe this issue has already been reported?

If you search the email archive, you'll find some past threads about the issue. (I don't have an answer to your question. I only remember there have been such threads, but there are people who are much more knowledgeable about contour labels than I am.)

Hope this helps,

Ryo

Have a nice day,

Serena Illig
