No one having a good solution to this one?

This is my graph:

rrdtool graph power_1hour_hour.png \
--start -3600 \
--step 60 \
--width 600 \
--height 400 \
--x-grid MINUTE:1:MINUTE:5:MINUTE:5:0:%H\:%M \
--y-grid 1:40 \
--units-length 3 \
--title "Last 60 minutes (1 hour interval)" \
--vertical-label "Watt usage per hour" \
DEF:totalHour=power.rrd:totalHour:LAST \
VDEF:totalHour-min=totalHour,MINIMUM \
VDEF:totalHour-avg=totalHour,AVERAGE \
VDEF:totalHour-max=totalHour,MAXIMUM \
VDEF:totalHour-last=totalHour,LAST \

LINE3:totalHour#000080:"Total usage" \
GPRINT:totalHour-last:"%7.4lf%Swatt" \
GPRINT:totalHour-min:"%8.4lf%Swatt" \
GPRINT:totalHour-avg:"%9.4lf%Swatt" \
GPRINT:totalHour-max:"%9.4lf%Swatt\l"

This gives me something like this graph:
