Hello guptamohit!

We appreciate you reaching out to us!

To update the chart you can create an updateFlag and then create a function that will change elements of the chart in chartOptions. Here you've got an example demo: ... -to-update

Best regards!

I am having issues trying to duplicate the code in my environment.

Is there a version of this code that works under Angular-16?

Hello stoshb,

Welcome to our forum and thanks for contacting us with your question!

This code also works on angular 16. If you have still problems with it, try to reproduce it in eg Stackblitz.

Demo: ... mponent.ts

I hope it was helpful
Best regards!
