Reply To: Update chart with new date

[Manoj Mohan]

@rcweb,

getJSON function is used to load/get the JSON from the URL not to send the data to PHP page. If you want to pass the date selected from calendar and fetch the data based on it, you need to perform post or get request using $.ajax to an API created in PHP which receives the date and return the data. You can then fetch the data received from the API using $.getJSON and pass it on the chart options to render the chart.

If you are still facing the issue, kindly create sample project reproducing the issue and share it with us over Google-Drive or Onedrive along with sample data so that we can look into your code, run it locally at our end to understand the scenario better and help you out.
