Kprobe graphics problem

I have a lite-on 165H6S with HV9N FW.
Running Kprobe 2.5.2
Driver set as ASPI
Kprobe test works fine, but when it posts graph, instead of nice clean lines I get boxes of text.

Is there a setting in Kprobe or elsewhere I need to set.

Hey, never mind, figured it out myself.
Can’t figure out why show marks is the default setting.
