Ahhhh. I see.

So instead I should do:
/usr/local/rrdtool-1.2.27/bin/rrdtool graph images/speedday.png -l 0 \
-t 'Sync Speed - DAILY' \
-x HOUR:1:HOUR:4:HOUR:2:0:%k \
DEF:maxdown=modem.rrd:maxdown:AVERAGE \
DEF:maxdownmax=modem.rrd:maxdown:MAX \
DEF:maxdownmin=modem.rrd:maxdown:MIN \
    VDEF:ds2max=maxdownmax,MAXIMUM \
    VDEF:ds2avg=maxdown,AVERAGE \
    VDEF:ds2min=maxdownmin,MINIMUM \
    VDEF:ds2pct=maxdown,LAST \
 COMMENT:'            ' \

    COMMENT:'Average   ' \
    COMMENT:'Minimum   '  \
    COMMENT:'Last Value\l' \
    LINE1:maxdown#00F000:'Max In. ' \
    GPRINT:ds2max:'%5.0lf kb/s' \
    GPRINT:ds2avg:'%5.0lf kb/s' \
    GPRINT:ds2min:'%5.0lf kb/s' \
    GPRINT:ds2pct:'  %5.0lf kb/s\l'
