Hi ,
Thanks for your response .
I have updated the fiddle to show the issue i am facing when updating data labels dynamically.
In this fiddle
https://jsfiddle.net/shivaram1989/Lkpo2m3s/14/ , you can see when i update the data label font family by clicking on the button 'font family'.
The text in the data label is not aligned to center and sometimes it gets out of box when trying to change font family to Verdana etc.
I want the data labels to be always aligned at center even on changing the format or font size or font family.
