[rrd-users] Perl RRDs module: add second Y axe does not work ?

[Thomas Parvais]

Hello

I would like to add a second Y axe at the right with another scale with 
the following PERL code. (using RRDs module)

Unfortunately, it does not work the script stops on the argument 
"--right-axis 20:0"

Using RRDtool package 1.3.1 for my sheevaplug

Any idea ?

Thank you

Thomas
