PBI Tree Map Data Level Value

Hii neelpatel29 

In Power BI Treemap, there is no option to change data label orientation (vertical/horizontal). Label placement is automatically handled by the visual based on available space, and text may be truncated if the tile is small. You cannot manually rotate or reposition labels. To improve visibility, increase visual size, reduce category count, adjust text size in Format >> Data labels, or use Tooltip to show full values.

Hi,

Currently in Microsoft Power BI, the Tree Map visual does not provide an option to control the orientation (vertical/horizontal) of data labels.

Key Points

• Data label orientation in Tree Map is handled automatically by Power BI.
  • When the rectangle size is small, labels may get truncated.
  • There is no built-in setting to rotate or manually align text vertically or horizontally.

Workarounds

• Increase the visual size to allow more space for labels.
• Reduce the font size in Data labels settings.
• Turn off Category labels and show only Values (or vice versa).
• Use Tooltips to display full text on hover.
• Consider alternative visuals like:
  1. Stacked Bar Chart
  2. Matrix
  3. Custom Tree Map visuals from AppSource

If label readability is critical, a different visual type may provide better clarity than the default Tree Map.

Hope this helps.

Thanks!
