Loyal-Young opened a new issue, #6429: URL: https://github.com/apache/rocketmq-dashboard/issues/6429
### Environment rocketmq-studio at 779b8c0e. ### Reproduction A range-query series containing a scalar sample with value "" or whitespace is accepted as text by the backend. Metrics Explorer then converts it with Number(sample.value), producing 0. The chart, detail table, result summary and CSV all treat that absent numeric value as a real zero. Histogram parsing already rejects blank values through finiteNumber. ### Expected Blank scalar samples should follow the existing invalid/non-finite sample handling and not manufacture a measurement. Real zero, signed decimal and scientific-notation samples should remain visible. ### Proposed fix Use the same finiteNumber conversion for scalar samples, with regression coverage through chart samples, summaries, detail rows and CSV rows. Duplicate searches for blank metric samples found no matching fix. AI assistance was used for source inspection and drafting this report. -- This is an automated message from the Apache Git Service.
