I have a photovoltaic and want to display the generated power of last day and the current values in the same chart. The reason is e.g. - especialla on days like now - to see, at which time I get a power boost and also to compare values to previous day.
-
Is this possible?
-
I tried something e.g. with persit-node. Here my last try with error output:

I get the error:
msg : error
"TypeError: oldValue[0].values.data[s].push is not a function"
So perhaps my change-node is wrong:
Thanks for all comment and help
