Fix type error in Analytics

Fixes a type error in Analytics.tsx related to the tickFormatter in the YAxis of the BarChart component. The tickFormatter was receiving a string value instead of a number, causing a TypeScript error. The fix ensures that the value passed to the number formatter is indeed a number.
