Customizing Oracle APEX Bar Chart Tooltip Text Colors Based on Value

sonali5 days ago

I'm working with a bar chart in Oracle APEX that displays ACB Opening and Net Churn percentages. Currently, I've implemented a custom tooltip that shows these values when hovering over chart elements:

'ACB Opening : ' ||TO_CHAR(SUM(ACB_OPENING),'99,99,99,99,99,999') ||chr(10)|| 
'Net Churn % : ' || TO_CHAR(round(((((SUM(ACB_CLOSING)-(sum(NC_MTD)))- SUM(ACB_OPENING)) / SUM(ACB_OPENING))*100),2), '99999999900.99') || '%' as tooltip

Current Implementation:

  • The tooltip successfully displays the values
  • The formatting works as expected
  • Values display in default color (black)

Desired Implementation:

  • I want the ACB Opening and Net Churn values to display in:

    • Red color when negative

    • Green color when positive

      Is it possible to apply conditional formatting to specific parts of a tooltip in Oracle APEX charts? If so, what's the recommended approach?
