Gauge Chart is not showing any readings

Development Data Visualization

Though while typing the code for gauge chart didn’t show any kind of error or ‘crosses’ on the side, after deploying and refreshing the graph page, alert message is showing:-
" Please check the plotChart() function in your product code
Undefined variable name light_data".
This message is still there even after copy-pasting the code given.
Can someone please help cause it’s not showing any readings on the gauge? It is fixed on 3
Also my setAxisName type is same as variable name

variable name and code

@mani2474695 This is the code sir
setChartLibrary(“google-chart”);
setChartTitle(‘Gauge Chart’);
setChartType(‘gauge’);
setAxisName(‘light_data’);
setDimensions(400, 400);
setMaxValue(1023);
setGreen(250, 500);
setYellow(501, 725);
setRed(726, 1023);
plotChart(‘light_data’);

Thanks a lot :grin: it is working. But it makes me wonder why just changing variable name from ‘light_data’ to ‘light’ made it work. the doc doesn’t mention about such anomaly.

beacuse light_data was not your variable name
your variable name was light
light -data was your product name
hope you understand the diffrence between product name and variable name
