Hey Guys, I am a student and trying to develop an app using app template. I am facing problem related to timeseries.js library. Whenever I try to append value using append function , I get the following error.
" timeseries.append datastore[valve_position_1] is undefined " .
valve position 1 is already configured in config.app and it is being updated when ever I change the feed value.
can smeone help me in solving this error. I already checked timeseries.js library and couldn’t figure out the problem.
I am using mysolarpv.php as a reference.
