Analog rating scale

Dear All,
I am using digital rating scale from 0 to 10 or -5 to +5, but I would like to introduce Analog rating scale in my experiment. For example, it can store and show results like 1.5, 0.6, 0.9, 9.9 something like these. I have looked on Psychopy documentation but I was not able to find the solution. Can someone give me some advise, How to get analog scale?
Thanking you.
