GitHub user dosubot[bot] added a comment to the discussion: radar chart min and max values
<!-- Answer --> You can use D3 format strings in the Superset UI to customize how numbers are displayed in charts, including radar charts. For example, you can show negatives in parentheses or adjust decimal places. However, if you want to add a completely custom number format (like hiding the minus sign or applying special logic), you need to extend Superset's frontend code by creating a new number formatter and registering it in the formatter registry. This involves writing a custom format function in JavaScript/TypeScript and updating files like `setupFormatters.ts` in the codebase. There isn't a built-in UI option for end users to add arbitrary new formats beyond D3 syntax—custom logic requires developer changes and a redeploy. More details and examples of adding custom formatters are shown in recent pull requests ([example](https://github.com/apache/superset/pull/30593), [example](https://github.com/apache/superset/pull/30559)). <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
