Gauge Chart - No Data To Display

[#1]

Is there a way for me to display a blank traffic light with no colours if no data is present currently it shwos the text - no data to display. Please see attached picture as you can see stand 12 has a text image in replace of the traffic light as no data is present.

Try using the alt function so your expression never returns null: alt( expressionhere , 0)
