hi girls and guys
i am busy the whole day to generate a graph from my database but not able to fix this....
Currently my database has 2 entries ( just for test purpose )
In the future there will be more entrys.
Output from my sqlite3 command is:
sqlite3 test.db "select timestamp,value from temperatuur order by timestamp;"
1605720348906|20
1605720358906|210
I know the code is not correct and the "setup payload" has to change.
I was busy whole day to figure this out...but without any success.
Just want to make a graph of this 2 entrys.
I hope some one can help me out here.
many thanks in advance
Menno
