Hi,
I have graphs of connected wifi cients per AP.
I want to add the values togehter into one line in a graph to see the total of connected wifi users in my network.
Any suggestions in how to add those values together ?

regards,

Eddie

If the graphs have the same y-axis metrics then they overlap automatically in the graph page of the device. I use that for voltage and temperature graphs...

Hi,

The 2 lines in one graph is not a problem, but I want to stack the values to see a maximum in the graph ...

i have used the dude chart function to add many sources on one graphic to get the graphic you mention

The screenshot below shows a graph with 2 lines from separate devices. I want to stack them, not to show them side by side ... I can not find a wy to do that ...
So 1 line with the total of both devices added together.

in chart data sources you have to create a new one adding the multiple snmp values you already have using oid codes () and +

once you have that data source created you can add it to a chart

sorry not having more precise information I no longer have access to those implementations

The 2 OID are from different devices ...
I know that would be the direction to look into, but I can not find how to add snmp oid from 2 (or more) devices into 1 datasource ...

Found it ...
not that hard after all, tnx for the suggestions.
create a datasource for device "none" and put some function code inside
create a graph for this new datasource

I'm glad you did it, those graphics are very useful
