MATLAB: How to make gauge value variable

Question

I created two gauges using App Designer. Went into corresponding gauge codes and change the value to constant value such as 19 and 54 just as given in the pic below. However, what I want is a moveable arc. For example 'gauge' goes from 0 to 45 smoothly and changing between 45 to 35 as long as I keep open the app. How to achieve this? Gauge code doesn't allow me to edit on code so I couldn't play with it. :/ Any ideas?

You can programmatically change the properties of a gauge. For a list of properties, see this page.

The code might look something like this:

app.Gauge.Value = var;

Any time this code is called in your app, it will update the value of Gauge to be the current value of var.
