GitHub user dosubot[bot] added a comment to the discussion: translation file has not taken effect and the chart data is missing in the local language
<!-- Answer --> For the table chart time comparison columns: only the "Main" (or "SUM(Metrics)") column label is localized via translation files; the other columns (#, △, %) use hardcoded symbols and cannot be globally customized through translation files. However, you can set custom names for these columns individually in the chart's "Customize columns" (column_config) UI, including hiding the symbol by setting `displayTypeIcon` to false [[source](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-table/src/TableChart.tsx)]. The issue where the "Main"/"SUM(Metrics)" column shows blank data in non-English languages is a bug: the frontend generates data keys using the translated label (e.g., "主 <metric>"), but the backend always sends data with keys like "Main <metric>". This mismatch causes the data to disappear when the UI language is not English [[source](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-table/src/transformProps.ts)]. For translation effectiveness: starting with Superset 5.0.0, Docker images must be built with `BUILD_TRANSLATIONS=true` for translations to work, especially for chart plugins. Make sure you edit `.po` files (not `.json`), run the translation build scripts, and confirm that all necessary translation keys are present in your language files. Some UI elements may remain untranslated if their keys are missing or hardcoded, which is a known limitation [[source](https://github.com/apache/superset/discussions/34540)]. If you need to avoid the symbols or want more control, use the per-column customization in the chart UI. For the missing data bug, the only workaround is to use English or avoid time comparison columns until the frontend-backend key contract is fixed. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
