Guages panel question?

I am a novist when it comes to editing panels. I am able to add gauges and remove them just fine. However, there is a set of numbers after the guage name that does not make sense to me. For example
Gauge01= C172adi, 123, 456, 789, 012
What do the last set of four numbers mean in the series above. and how do I use them? I am sure it is size of the gauge and location. I am not sure which is which. Would you please tell me?
Thank you very much.
