                ^  Isn't this your problem?  Zero isn't valid here.

I think the 'period' parameter should be your p3 or some other suitable
interval.

I hacked up a minimal test 'displayk.csd' that works fine:

<CsoundSynthesizer>
<CsOptions>
-odac     ;;;realtime audio out
</CsOptions>
<CsInstruments>


instr 1

printf_i "p4=%d p5=%d\n", 1, p4, p5
knh	line p4, p3, p5
display	knh, p3

endin
</CsInstruments>
<CsScore>

i 1 0 1 10 20
i 1 + 1 0 3
i 1 + 1 150 1
e

</CsScore>
</CsoundSynthesizer>

 
Then run:

   csound -G displayk.csd

and you get a file 'dac.eps' that has the graphs.

For some reason you get ascii graphs in the terminal as well,
which I can't find a way to suppress, but the graphs are correct.
