When using Gantt chart visualisations in Oracle Analytics Cloud, the timeline/date labels are displayed in a fixed black font colour. This creates a readability issue when dashboards are designed using a dark theme, as the labels can become difficult or impossible to see against darker backgrounds.
Currently, there does not appear to be an option to customise the font colour of the Gantt chart timeline/date labels.
Enhancement Request:
Add a formatting option that allows users to customise the colour of timeline/date labels, or have them automatically inherit the dashboard theme's text colour.
Benefits:
- Improved readability and accessibility for dark-themed dashboards.
- Greater flexibility in dashboard design and branding.
- Consistent formatting capabilities across OAC visualisations.
- Better user experience without requiring theme compromises or workarounds.
Use Case:
A dashboard built with a dark background uses white text throughout for readability. However, the Gantt chart timeline dates remain black, making them difficult to read and reducing the effectiveness of the visualisation.
