last to lines of my "rrdtool graph" command are already following:

GPRINT:HDD0:MAX:"Max\: %5.2lf" \
GPRINT:HDD0:MIN:"Min\: %5.2lf\n"

..but when I generate a graph, watermark part still looks like this:

If I increase the "--width" value, the watermark moves to the center:

makes the graph very large and that's not exactly what I want. If I
add another "\n" to last parameter like this:

GPRINT:C4506_chassis_DEF:MIN:"Min\: %5.2lf\n\n"

..the image will look like this:

simple solution to add blank line to the graph legend? Or anything
else to try?
