Chartjs-Send data from php to chart with ajax

You’re probably going to want to use AJAX requests to fetch the data and show it on your webpage. In your Javascript file, you request data in a JSON format, which can then be processed by your js script.

I found a tutorial for this at https://phppot.com/php/creating-dynamic-data-graph-using-php-and-chart-js/, that uses the JQuery $.post() method.
