Chart - The bar is not rendered if the value is 0 (or near 0)

Chart Tooltip is returning error when data is near 0

created 2 years ago

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

Hello,

Thank you for bringing this to our attention. I created a bug report: T1176892: Chart - If the value is 0 (or near 0) bar does is not rendered. You will be notified once we have updates.

As a workaround, set minBarSize to 1 to force-render a bar with low values. I created a CodeSandBox sample to demonstrate the approach.

Regards,
Assylbek
