    Hello,
    I am using an ESP32 aka NODEMCU micro-controller and it is hosting a webserver on it. I am reading DS18B20 temperature sensor and displaying on the html page. This works great but I am trying to incorporate your live dynamic charts to chart the value of the temperature sensor reading. Aka chart the temperature. I have tried for 2 days and cant seem to get it to work. It displays no problem on the webpage/html page but I don’t know how to get that value into the canvasjs charts and couldn’t find any helpful resources. We potentially want to use this for a commercial project in the future but have to prove the concept to my boss first and I love these charts so trying to avoid going with someone else.

    Thank you,

    @zebrawolf,

    Please take a look at this documentation page for step to step tutorial on creating a dynamic chart using data from JSON API.

    If you are still facing the issue, kindly create a sample project reproducing the issue you are facing and share it with us over Google-Drive or Onedrive along with the sample data so that we run the code locally, understand the scenario better and help you out?
