pipe gnuplot + while read does not behave as expected

Hi folks, hope your all well.

I'm piping the output from gnuplot and want to log each line of output separatly. This is what i have so far

Code:

gnuplot $CMD 2>&1 | while read line; do 
    log $line
done

Looks simple right? I'm assuming that read parses newlines

Problem is the log is like this

Code:

${log prefix stuff}: FIRST LINE OF ERROR
NEXT LINE OF ERROR
NEXT LINE OF ERROR
...

etc etc and so forth.

Anyone have any genius idea I completely missed?

Regards
G

:Edit
Should have said that the logging function works fine in about 200 other places im using it. Throw it a string and it records it and prints it the way its supposed to.

What did you expect to see? Something like this?

Code:

${log prefix stuff}: 
FIRST LINE OF ERROR
NEXT LINE OF ERROR
NEXT LINE OF ERROR
...

What OS are you running?
