WebUX Trend Visualization Issue - WinCC V7.3

Hello,

You're experiencing an issue where trends display correctly in the WinCC V7.3 Runtime but appear empty in WebUX. This is a known limitation. Based on the documentation you referenced, WebUX has limitations regarding certain trend display features.

Specifically, filled trends, limit lines, and the "Display values" trend type are not fully supported in WebUX for WinCC V7.3.

Workaround/Recommendations:

  • Simplify Trend Configuration: Try using a basic trend configuration without filled areas, limit lines or value display. Use just the line itself.
  • Consider alternative visualization: For complex trend visualization, consider using other WebUX components or reporting tools.
  • Check SiePortal: SiePortal provides further information and potential updates regarding WebUX limitations. Search for "WinCC WebUX trends"

If the issue persists with a simplified trend, please provide more details about your trend configuration (trend type, options enabled) for further assistance.
