### Body Currently, it is possible to select multiple data sets for a single chart. While this feature aims to provide flexibility, it introduces significant complexity and usability challenges. In practice, combining multiple data sets often leads to issues in configuring the visualisation correctly, especially when: * The underlying data schemas differ * Different aggregation levels are used * Data is not directly comparable This makes it difficult for users to create meaningful and correct visualisations. **Problems:** * Complex and error-prone configuration * Inconsistent schemas across data sets * Confusing or misleading visualisations **Proposed Direction:** * Remove support for selecting multiple data sets within a single chart * Encourage users to merge or join data streams within Pipelines instead * Ensure that charts operate on a single, well-defined data set **Rationale:** Handling data merging at the pipeline level provides: * Better control over schema alignment * Clear and explicit data transformations * More predictable and maintainable visualisations **Open Questions:** * Are there valid use cases where multiple data sets in a chart are essential? * Would removing this feature significantly impact existing dashboards? ### StreamPipes Committer I acknowledge that I am a maintainer/committer of the Apache StreamPipes project. -- This is an automated message from the Apache Git Service.
