Perf plugin issues

[Dottor Gonzo]

Hello everybody!
I'm trying to use the perf plugin on a Windows 7, 64-bit italian computer but I have some issues.
I can successfully obtain an horizontal graph showing the total processor time, but I can't do the same thing with a vertical one.

Here's what I did.

Horizontal graph:
$dll(perf,1,1x20#r#2#5#0#100#\Processore(_Total)\% Tempo processore,Test)

First question: what's the meaning of "Test" on the end of the command line? I can change it with any other words, and the graph still shows correctly.

Attempt with a 2 line high vertical graph:
$dll(perf,1,2x20#u#2#5#0#100#\Processore(_Total)\% Tempo processore,Test)
$dll(perf,2,\Processore(_Total)\% Tempo processore,1)

The second line shows: [No such graph]. If I add "Test", like this...
$dll(perf,2,\Processore(_Total)\%Tempo processore,Test,1)
.... it shows "Too many parameters"

What did I do wrong?
Thanks!

I solved like this:

$dll(perf,1,2x20#u#2#5#0#100#\Processore(_Total)\% Tempo processore,Cpu)
$dll(perf,2,Cpu,1)
