[rrd-users] legend: getting everything aligned and perky

[Ulf Zimmermann]

You can use \t in the GPRINT to align.

I use the following, which seems to be the same as your output, minus
the header line:

AREA:rhigh#FF6666AA:"High  " \
LINE1:rhigh#FF0000 \
GPRINT:rhigh:AVERAGE:"Avg\\: %7.2lf" \
GPRINT:rhigh:MAX:"Max\\: %4.0lf\\n" \
AREA:rmedium#6666FFAA:"Medium" \
LINE1:rmedium#0000FF \
GPRINT:rmedium:AVERAGE:"Avg\\: %7.2lf" \
GPRINT:rmedium:MAX:"Max\\: %4.0lf\\n" \

The environment I'm using requires me to escape colons, so you might not
need those extra \\'s before the colons.  The important thing to
remember is to include your format string in quotes, so that you can
manually add extra space where necessary.  For example if you wanted to
spell out the word "Average" instead of "Avg", you would need to change
the "Max:" to be "Max    :" instead, etc.

Good luck!

Or if the name of area2 has more characters everything else gets bumped.
