Deneb Gantt Chart

[suvoda]

I have used this deneb gantt chart github code by David. I have the following fields - start, end, id, dependencies, phase, task. I have this functionality where when I select on a task in the chart, the task name is displayed in a card visual. This functionality works good, but whenever I drag down and click on a task, the entire visual resets to its original state. Is it possible to freeze the visual to wherever I have dragged it to or in my current position, instead of reseting.

Thankyou, @Akash_Varuna, for your response.

Hi @suvoda,

We appreciate your inquiry posted on the Microsoft Fabric Community Forum.

Based on my understanding, currently Power BI does not support preserving the scroll or zoom position within custom visuals such as Deneb following user interactions, for example, selecting a task. This occurs because Power BI re-renders custom visuals upon interaction, which results in resetting the visual state.

Please consider the following workaround which may help to address the issue:

To maintain a stable scroll view, we recommend externalising task selection. You may use a slicer or table visual external to the Deneb chart to select tasks. This approach enables the Gantt chart to remain static without resetting, while simultaneously updating the card visual with the selected task details. This method ensures a smooth and consistent user experience while working within the current platform capabilities.

Hi @suvoda I don’t think it is possible to directly "freeze" the visual position in Power BI after dragging, as interactions like clicking and dragging usually reset the visual state. However, you could use bookmarks to save and restore the visual’s position. Adjusting visual interactions or checking Deneb's Vega-Lite configuration might help maintain the desired view state. Syncing slicers can also prevent resets if slicers are involved.
