Re: Tabel

If you want to display how distribution of temp into the buckets you have defined changes from month to month the predefined chart "_tempdays-1year" might be worth a look. Here buckets don't need to be equidistant and you might be able to have multiple sensors in one chart. Lots of options to change...

Re: Tabel

Hi, that should be possible with same options that generate weibull charts for distribution of wind speed into definable buckets. Intermixing multiple sensors into one chart/table might not be possible and buckets will nee to be "equidistant". You might try this definition: timeframe=-1M # set total...

Re: Negative rain?

Negative rain is indeed something funny :P I looked at your setup. You have two rain sensors in operation. rain0 has a total counter value of 406.6mm rain1 shows total counter value of 656.1mm On the settings page I can see that an offset of -458.8mm is applied to sensor rain0. Having that it is "lo...

Cumulative Rain Graphs

By adding parameter "scumul" to a sensor definition, you can make graphs that don't use values of each time bucket but does adding up these over the whole selected period of time. This can be useful to generate stairway graphs for total rainfall. Definition "_rain-1month" does also use this feature ...

Re: New Chart-Type Weibull

No, you are right. I added handling of "gtrim" value to distribution charts which allows to strip empty buckets from the output. That part had an error, filtering out all buckets with value in it. :oops:

It is fixed now. Please give it a second try.

Re: New Chart-Type Weibull

I just added "xfactor" and "xoffset" values for that. to get x-axis in km/h use: xstart=0.0 xinc=0.27777 # data gets collected from data base in the original unit (here m/s, so increments are 1/3.6) to make 1km/h steps xfactor=3.6 # factor used to stretch results when being displayed xoffset=0.0 # c...

Re: New Chart-Type Weibull

I did fear that this will be asked :-)
No, not at the moment. As factors and offsets don't apply to that x-axis values,
it would need an additional mechanism to make that happen.

New Chart-Type Weibull

Weibull-Graphs show how long a certain sensor value has been received. Putting that into a graph shows distribution of values. This is extremely useful to make a prediction of how much power a wind power generating device might produce at this location (when you make Weibull on wind speeds). This ty...
