Hi Vincenzo
There is no specific limit on the amount of data you can pass.
Depending on the computer, as the data gets larger(for example 10,000+ records), the webpage may start loading slower.
You can have a look at the demo here: https://jsfiddle.net/sb3nkjph/1/
By changing the number of loops, you will see that the chart works perfectly even with thousands of records.
If you have any other questions, please do not hesitate to contact us again.
