A few people wish to see a graph with cumulative rainfall.
I just noticed that an old graph I use isn't showing the rainfall cumulative like it did before I changed to Meteohub.
It now shows the rainfall in spikes.
I guess this means that the clientraw generated by Meteohub is missing a data string which containes the cumulative amount of rainfall !?
Maybe it only takes a small change to also be able to create cumulative graphs!?
Mir geht es genau so. So wie der Regen dargestellt wird, ist es für mich nicht so aussagekräftig. Eine kumultative Anzeige für Regen wäre für mich wirklich ein Muss.
Cumulative means that you can see very easy on the graph when it started raining and how fast it was raining. In the Meteohub graph you only see spikes.
See the attached image where you see the cumulative rainfall as a red line.
Boris once said that is was very difficult to make something like this because of the update interval. With Meteohub it isn't realtime.
showing rainfall in a stairway like curve that increases with each rainfall over a given period of time is very hard to realize as Meteohub does not provide that kind of data.
When you look at aggregated data format, you see that meteohub reports values for average, min and max values of each time bucket. This data gets more or less directly fed into gnuplot, which creates some graphs on this. Planing to do a stairways display would mean that additional math has to be applied when feeding that data to gnuplot, namely starting at zero level with the first requested record and adding up increments. This will need another computational stage at a point in processing where this has not been before with lots of side effects etc. Up to now all computation has been done in preparing aggregated data, not in doing additional math on that when requested to be graphed.
To make a long story short, I don't feel the benefit of having this is worth the implementation effort and additional complexity in design.
I will give it a thought, if the database layer of Meteoplug could handle that for me. In that case I have a very capable sql layer between selecting aggregated data and punching this out to the graphing engine.
Für die Ausgabe in WD-Live liesse sich das vermutlich leicht ändern. Ich schau mir das mal an.
In Meteoplug habe ich generall das Feature zur Kumulierung von Werten in Grafken (vermutlich nur bei Regen sinnvoll) rasch implementieren können. Details hier: http://forum.meteoplug.com/viewtopic.php?f=9&t=22

Wenn es dies auch noch für die Evotranspiration einer VP2 geben würde wäre spitze
auch ich bin auf der Suche nach der Möglichkeit den Regen als Verlaufsgrafik darzustellen.
Da ja scheinbar doch Nachfrage bei den Usern besteht, wäre es toll wenn Boris vielleicht doch noch mal etwas Zeit für dieses Feature investiert.
Die Aufaddierte Regenmenge gibt es ja schließlich. Muss ja "nur noch" der zeitliche Verlauf mit rein...
