I want round off these percentage values.
for instance 27.94 shown as 28%.
Hi @varnika
There's a request open for that:

on the first post
When we will get this feature or any other way to round off the percentage values in Pie chats?
@varnika There are 2000+ other issues, so I cannot tell you when or even if this will be implemented.
The only workaround would be to build your own version of Metabase, or use a different visualization.
