While I only wrote a single line of code why does it show this error.
plotChart(“time_stamp”,“light”)
check this forum they have discussed about this issue and solved it
To plot chat in bolt cloud , you need to define these functions first:
setChartLibrary('google-chart');
setChartTitle('Your chart title');
setChartType('areaGraph');
plotChart("time_stamp","light");
Do try this and let us know. If you still face issues please feel free to get back to us
