Hi,
I’m able read data from my PV about production as value “Yield yesterday”, it looks like this :
I want make a bar graf about production for each day, but not clear for me how to do it.
Please can you help me ?
Thank you
Alex
Mine looks like this. Then I use the total production from each inverter.

Thanks
looks very nice, let me check.
Is it possible place into one day into two bars a total production and total consumption ?

WOW
THANKS a lot
problem is that I think it’s day to day difference :
edit: I changed to maximum and looks ok
one additional question,
is it possible have a bar as sum of two values ?
like production1 = 5kWh (blue) production2 = 2kWh (green), complete bar = 7kWh ?
Yes see my first post
ohh, sorry my error. I thought it was one over second.
But for me not working
looks like it’s working only when value is still increasing, but for me goes to zero in midnight or hold a value complete day
Please post your code 
I want ask one more question. I want show in the graph sum of two items. Is it possible make a sum directly in the graph definition somehow or I must make a new special sum_item for this sum and then make a graph from this sum_item ?
I use Number:SUM on the group I want to show. See first code above for the use of gSolcelle_E_tot
Group:Number:SUM gSolcelle_E_tot "Måler inverter" <solarplant> (gService) ["Inverter"]
not clear for me where to place. This Group I will place into chart page code ?
I have a Group containing all three values I want to Sum, if you then use Group:Number:SUM in the definition of the group, you can use the group name in the chart
You probably have to wait until tomorrow before it starts to show, it does not sum up past values, if I am not mistaking.
Then add the Items you want to SUM to this Group, and use Group name in bargraph instead of Item name
I have only two items defined like this :
how did you created this group ?:
