Simple way to display a variable on Unicorn Hat HD

Hi, I’ve got my BME680 set up on a PHAT STACK with my Unicorn HAT HD. I want to combine the two and display the air quality reading on my Unicorn Hat HD. Typically the number will be a percentage say 95%. Is there a simple way to achieve this as I’ve searched through various scripts and can only see text being displayed. Thanks in advance Scott
