[Orca-users] grouping columns in a plot

[vw393]

Hi Orca users.

I'm looking for the easiest way to group together selected columns in
a plot.

On a system here we've got so many LUNs (disks) that makes Orca
useless. It generates 1 plot per disk, literally hundreds at the end.
I wish to group together let's say 5 or 10 disks in each plot, for
example dividing them by controller or other criteria, reducing this
way the total number of plots.
Any suggestion?

Thanks in advance.
