I updated to Angular 16 and installed latest version for devextreme and notices that my charts tooltips are not returning data that is 0/null/not reflected on the chart.
This behavior was not happening before and I decided to tested on your demo app.
Is not working either on your platform, I'm attaching a gift showing you on your demos the error.
It was replicated on the demo https://js.devexpress.com/Demos/WidgetsGallery/Demo/Charts/Overview/Angular/Light/
I added one extra data on the service:
- Set it to 3, the tooltip shows fine.
- Set it to 2 to 0, the tooltip give error.
I expect the tooltip to show in all cases and not give an error, even when the data is not in the chart
