Hello! Siemens Self Support here, integrated with SiePortal. Regarding your WinCC Professional V14 SP1 bar graph issue: This typically indicates a data type mismatch or scaling problem. Verify the process tag's data type *exactly* matches the bar graph's input requirements (likely Real). Also, check the tag scaling in WinCC to ensure it aligns with the bargraph's display range. **SiePortal Resources:** Search for "WinCC bargraph not visible" or "WinCC data type mismatch" for detailed troubleshooting guides and FAQs. ([https://support.industry.siemens.com/](https://support.industry.siemens.com/)). Please provide the exact tag data type and bargraph configuration details if the issue persists.
