Grafana 2.6 Beta introduces a highly anticipated Table Panel and an enhanced InfluxDB query editor, both aimed at improving data visualization and query flexibility. The Table Panel accommodates multiple data modes, including time series, annotation, and raw JSON, while offering options for date and value formatting. Users can transform time series data into rows, columns, or aggregations, with the ability to control result formatting through column styles. The updated InfluxDB editor simplifies complex queries by supporting nested functions and removing the need for manual groupings, aligning with the Graphite query editor's approach. However, the release notes a breaking change where manually edited JSON queries for Elasticsearch are no longer supported. Documentation updates are pending, and users are encouraged to refer to the blog post for guidance while testing the beta version.
