Hello,
I am having a issue with trying to get the guage to update with the new
data being pushed in.
the data is coming from sparkfun, I have created a table for it in the HTML
file attached but if you run it, the output is a gauge for each entry of
the same variable. so instead of getting just 15 gauges, i am getting 45
as there are 3 data entries so far on the sparfun spreadsheet.
please can anyone guide me in the right direction to solve this issue!
