Gantt Visual (Microsoft) sorting issue and rendering differences between Desktop and Service

Hi,

I’m experiencing an issue with the Microsoft Gantt custom visual in Power BI.

Current scenario:
- In Power BI Desktop, the available version of the Gantt visual is 3.0.12.0
- However, the latest version released is 3.4.5.0
- I am using the Microsoft Gantt visual imported into my report

Issue description:
In Power BI Desktop:
- The visual respects the alphabetical sorting of my “Berth” field (ship berth name)
- Everything renders correctly

In Power BI Service:
- The sorting is not respected anymore (it appears unsorted or differently sorted)
- The visual quality (resolution/sharpness) is noticeably worse

Steps:
1. Sort the visual by berth name (alphabetical)
2. Publish to Power BI Service
3. Open the report → sorting breaks and rendering degrades

Expected behavior:
- Sorting should be consistent between Desktop and Service
- Rendering quality should remain the same

Additional notes:
- This seems related to differences in visual versions between environments
- I can provide screenshots showing the discrepancy

Has anyone experienced this? Is there a known limitation or workaround?

Thanks.

@rfcantarino Hi!

What’s happening is usually a mix of:

Different visual versions between Desktop and Service
The visual not consistently respecting sort order in Service
Rendering differences

You can try:

Create a Sort by Column (e.g. index/rank for Berth): Instead of relying on alphabetical sort in the visual, create a dedicated sort column (e.g. index or rank) and use Sort by Column. This is usually the most reliable workaround.
Remove and re-import the latest version of the visual
Avoid relying on visual-level sorting, let the model control it

Hello @rfcantarino,

This is expected behavior with custom visuals like the Microsoft Gantt chart.

Power BI Service often does not preserve visual-level sorting from Desktop. Because “Berth” is a text field, the order can change after publish.

Fix it in the model instead. Create a numeric sort column (BerthSortOrder) and apply “Sort by column” on BerthName.

Rendering differences also happen. Desktop renders locally, while Service runs the visual in a browser sandbox. That can change sharpness for some custom visuals.
