[mrtg] keeping the peak with just 2 values

[chays]

My sincerest apologies if this is answered elsewhere -- Ive scoured the list
archives and am still confused.

Here is the page:

http://www.whoo.org/mrtg-things/weather.html

and here's the code:

Target[weather]: `/path/to/file`
MaxBytes[weather]: 200
Options[weather]:
gauge,nopercent,growright,nolegend,nobanner,noinfo,nolegend,pngdate,noborder,noarrow
Title[weather]: Current Temperature in Fahrenheit (55106)
YLegend[weather]: weather
ShortLegend[weather]: &nbsp
WithPeak[weather]: wmy
LegendI[weather]:  Temp in F:
LegendO[weather]:  Humidity %:
Colours[weather]: GREEN#A24638,BLUE#3895A3,DARK GREEN#006600,VIOLET#ff00ff

My 'problem' is removing the 2 extra graph lines that are visible and
continuing to display the peak values. What am I missing, please? And for my
own understanding, while this isnt an issue on my other graphs, I am curious
what the extra 2 lines are actually graphing?

Thank you very much for any help.
