Bullet chart customization

Hi,

I created a bullet chart displaying two measures and an additional numeric value (currently as a second dimension)

Is there any way to display the numeric value in the category label like a traffic light (or colored/highlighted)?

This is the template (but not build with UI5)

The SDK Example for chart customization is not really helpful (only for bar chart and not all used scripts are shown).

Thanks in advance and best regards

Dominik
