How to combine sensors in single graph?

Is it possible to combine a Tempearture Sensor and let's say Gas Usage in a single graph?
If the answer is yes, can you explain how?
Thanks...

i guess you already know the answer of this as you did not find this option.
Please propose a patch that does this

Nope, I didnot know. But now I do... hm, let me think about this.
The thing I want to to is to visualize the temperature sensor (virtual weatherstation) and the gasmeter readings in a single graph.
So I was thinking that it might be possible to combine two "sensors" in a single sensor field.

+1 maybe in a simple reporting module ?

So has anyone that responded a suggestion how to solve this? Seen a library or a other open source project that we could look at to take the reporting module from?
Anyone?

I would say start with the same units (so for example kWh). I think that would be less complicated because it's the same like the temp graphs.
As i have no programming skills I'm not able to select a useable graph software but maybe someone else can and use the list below as a startpoint.

Yeah, great idea!
I would love to combine my electricity consumption graph (via P1-USB) with the energy produced by "Winddelen" (windmill) graph.
So, what is used versus what is produced.
Both graphs are available in Domoticz, but unfortunately in separate windows/charts.

While this would be a cool new feature, meanwhile, you could still make your own graphs using the json api, a custom page and a graph libray like jschart.
The custom graphs pages in Domoticz all call a URL like http://domoticz_server/json.htm?type=graph&sensor=temp&idx=8&range=2015-10-22T2015-10-29&graphtype=1&graphTemp=true&graphChill=false&graphHum=false&graphBaro=false&graphDew=false&graphSet=false
This solution needs you to get your hands dirty, but it also corrects one bug on custom graphs : The colors always stay the same

Maybe
https://github.com/Egregius/PHP-Custom- ... r/temp.php can lead to a solution.
It shows a graph of room temperature together with the setpoint.

I use a dummy "p1 smart meter" to combine my two solar strings, one as tariff 1 and the other as tariff 2. Because domoticz thinks it is a smart meter, it automatically adds the two values for the daily result. This only works if you have not more than two inputs. I would rather have a custom graph possibility where you can choose the number of inputs and if domoticz should add them up or not (during the (live) present day or only in the graphs of the previous days. I think there are plenty people that want to combine/add measurements.

I see there is something now in the latest release that allows to show Produced and Used values on one graph.
How is the data for used energy to be fed into the sensor?
I am using json integration fed from my Goodwe inverter but would love to also present values from Aeotec HEM 2 on one graph.

It would be surely a cool feature, but, it will require quite some thought and tinkering on how to implement it.
Even when I theoretically can add all this to Domoticz, for now its less time use just to export CSVs and analyse in Excel

if customs sensors can get more than 1 measurement types (for example temp/hummidity/barometer) adding multiple sensors can give a nice graph matrix

How about influxdb and grafana ?
