GitHub user dosubot[bot] added a comment to the discussion: How to add a new chart type in superset version 4.1.1?
<!-- Answer --> The histogram chart in Superset does not expose the setDataMask method in its transformed props because cross-filtering is intentionally not supported for this chart type. The main reason is that histograms use binned numeric data, which doesn't map naturally to the categorical dimensions required for interactive cross-filtering. The implementation omits setDataMask from both the props and event-handling logic, while charts like timeseries do include it for dimension-driven cross-filter events. There’s a TODO in the code to implement cross-filtering for histograms, but currently, custom cross-linked filtering isn’t supported without significant custom development ([source](https://github.com/apache/superset/pull/30176)). <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
