Re: Plotting error

Agnes,

I believe you have encountered an old error that has been fixed in version 5.2.1 of NCL.

What version are you running? (ncl -V)

If you are running V5.2.1 and still getting this error, then we will need a copy of your script and the data file(s) so we can run it here.

If you are running an older version of NCL, then you will need to upgrade. There *are* work-arounds to the problem, but they will not work in every case, so it's better to upgrade.

The problem sometimes results if you are drawing a contour plot that has lots of "twisty" contours, and then you shrink it down in size to panel several of them on a page. Sometimes a work-around is to make the plots slightly bigger. There are various ways to do this, but I would need to see your script and a sample image.

Thanks,

--Mary
