Ok, ill try to explain this.
Whenever someone runs one program on my computer, the program increses the
number in /var/www/htdocs/mrtg/ppl.count

What im basicly saying is, I want the graph to show me how many times the
program was started last 5 minutes.
Instead it only shows me how many times it was started total.
(So there's no use of the "max" "average" and "current" statements at the
bottom of the graph, as the max and current are always the same)

However, if I remove the "gauge" keyword, and leave only "growbits" the
graph doesn't show me anything at all.
current: 0 and nothing at all on the graph.

"cat /var/www/htdocs/mrtg/ppl.count"   gives me these 4 lines:

then, 5 minutes later
"cat /var/www/htdocs/mrtg/ppl.count"   gives me these 4 lines:

Workdir: /var/www/htdocs/mrtg
Interval: 5
Refresh: 300
Background[_]: #FFFFFF
#Options[_]: growright
Options[_]: growright, gauge
Target[people]: `cat /var/www/htdocs/mrtg/ppl.count`
Title[people]: Program Test being run
PageTop[people]: <H1>Program Test being run</H1>
Directory[people]: bla
MaxBytes[people]: 10000
YLegend[people]: Runs
ShortLegend[people]: &nbsp; &nbsp;

I hope I made this understandable.
