Hi all,

I have been setting up a rrd to record and graph some data. I am
having some trouble creating the labels/legend at the bottom of the

I have a PNG image attached which shows my graph output. As you can
see, it doesn't look very nice. My rrd graph command is below.

Any advice or tips on how to create nicer looking "columns" in the
text below the graph would be appreciated. I've been playing with
various TEXTALIGN and COMMENT entries but have been unable to make it
look nicer. I'm not sure what I'm missing.

Thank you!
