Hi!

I work on a small alternative weather station diagram with rrd. In this =
time i can display some values (temperature, rain ...), but with others =
i have mental problems.

When i will display Wind direction the graph should be see like the Wind =
dir (deg) Graph in http://owfs.org/index.php?page=3Dweather----owfsws =
(only a point for each value). Is that possible?

In wind dir i would like to display a normalized average of the values =
as additional graph (line as main wind direction). How can i do that?

When i will draw Wind speed, the graph has a dropout when Wind Gust is =
there. Is a mechanism in rrd who will delete values which are a lot =
greater or smaller then the last value (dequeues spikes)? If so, (how) =
can i disable this setting?

Thanks for your help!

Holger
