The system command is in there after some other stuff.  I have a bunch of
pearl that calls the DEF, CDEF, LINE, and so on for the graph and after I
have all the bits I want I string it together and echo it to the system
which creates the graph and can then be called by a web page.

Here is the exact command that the perl spits out:

rrdtool graph c:\fw14_internet.gif \
-w 800 -h 350 -v Bytes -t Internet --start -86400 \
DEF:Input=fw14.rrd:if2_input:AVERAGE \
DEF:Output=fw14.rrd:if2_output:AVERAGE \
DEF:Errors=fw14.rrd:if2_errors:AVERAGE \
DEF:Input_max=fw14.rrd:if2_input:MAX \
DEF:Output_max=fw14.rrd:if2_output:MAX \
DEF:Errors_max=fw14.rrd:if2_errors:MAX \
LINE2:Input#00FF00:Input \
LINE2:Output#0000FF:Output \
LINE2:Errors#FF0000:Errors \
COMMENT:"\n" \
COMMENT:"\n" \
COMMENT:"                   Average             Max           Current\n" \
COMMENT:"In"


Not sure if this image will go through the list mailer, but if not
basically the comment at the bottom only has one space between words
instead of many:
