[rrd-users] rrd graph - multiple graphs on one plot?

[Gregory Guthrie]

I wanted to have multiple data on one graph, and also add an
additional set of y-axis labels.

I'd like to have wind speed and direction on one graph, and have the
velocity labels as standard on the left Y-axis, but also add a
direction indicator (N S E W) scale label over the scaled
(0-360  =>  20-30) wind direction on the right hand side of the graph.

A site with a similar thing is at:
http:/ /www.iwindsurf.com/windandwhere.iws?regionID=100&siteID=1399
but they use icons for direction, I wanted to just plot it as a graph.

Thanks,
Greg
