Very simple!
When you define a gauge, in the cfg file, you have obviously to set where it gets displayed on the screen. To do that you have to define the coordinates of the gauge TOP LEFT corner (which are the first x, y two numbers) but you also have to specify gauge WIDTH (dx value) and HEIGHT (dy).

Hope this helps
