Ok, let me explain in detail because I think there's possible optimization there for sure...
GOAL: to graph in real time the values from csv file everytime it is updated. The csv is into a Respberry Pi, it has to be uploaded automatically to the web when the file refresh.
I did a graph with highcharts cloud -> export into html file -> upload that html file into the web -> edit html file to put the data source link. So every time the csv is updated it should reflect the new data into the html.
data source link: http://www.cram-iot.cat/7triagi2.csv
web with edited html pointing to de data source link: http://www.cram-iot.cat/index2.html
all comments are welcome
Many thanks in advance
