https://cloud.boltiot.com/static/js/boltCommands.js does not have the functions that you are trying to call.
Bolt Cloud has predefined functions that uses setChartLibrary, setChartTitle.
To use them, you have to directly save the file in .js format.
plotChart() is a function that is defined in https://cloud.boltiot.com/static/js/boltGraph-2.0.0.js But don’t try to use that too. It won’t give you any response.
Correct way is -
setChartLibrary(“google-chart”);
setChartTitle(“Temp_in”);
setChartType(“lineGraph”);
setAxisName(“Time”,“Temperature”);
plotChart(“time_stamp”,“temp_in”);
And save the file as in javascript extension to use the functions.
I have made a custom gauge graph without google-chart as a project. You can see over here - Solid and Angular Gauge (custom) with Bolt Data
