I had typed the gauge Graph exactly as shown in the gauge Graph tutorial but I am getting an error that their is a plotChart function problem and the variable i.e. ‘light_data’ is undefined. And also no output on the graph is visible.
Variable name is light name in the configuration but you have used passed light_data in the plotChart function.
It should be
plotChart('light')
Do let me know in case you need any other information.
