How to show actual range in title?

Hi, 

I'd like to show the actual range on DateTimeAxis in title, and update it when  there's a change.

How to do that?

Hi, Yuvaraj,

Great, hopefully, that would not need a refresh of whole screen.

Thank you.

Hi Zhu,

Currently, we don't have direct support to update the actual range in the chart title, because it requires setState and will rebuild the chart again. However, we have achieved your requirements in a workaround sample with the help of the TextField widget, we have stored the actual range from the onActualRangeChanged event and updated the actual range value to the TextField widget whenever you pan the chart with the help of onZooming callback. We have shared the sample below for your reference.
