About google chart library

While learning data visualization on google chart library the module is showing the data count 20 first but whenever i program it for line graph and view it after deploying it is showing data count to be zero i tried 2-3 times but the same issue is arising it is not showing the graph and showing data count to be zero.Help

don’t change the product each time just change the code for same product i think this is the reason, if this was not the reason send your codes , webpage , products pics

No it was not necessary now but remember these things now you may need this while you are doing machine learning we need large data sets over there

what should i do to get the line graph as showned in lecture


refer this link just understand the program flow and copy paste it in the code editor
change the parameters

No it’s not necessary but you can download if you wish.
