[mrtg] display item I cannot seem to fix.

[chays]

Hello,

The best example of what I am trying to "fix" can be seen here:

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

Notice that as the graphs go from day to year that the additional
colors are added inside the graphs?

I'm interested in making my weekly, monthly, and yearly graphs only
use the 2 colors that are seen in the daily.

Is this not possible?

Thanks much,

whoo
