# Plot with non-standard domain

I have data {x, y} where x starts at -25 degrees and goes up to +25 degrees in 1 degree steps, and then comes back down to -25 degrees in 1 degree steps again.

I want to plot this sinusoidal-type data without the y-data overlapping in the ranges -25 - +25 degrees. I have attached an image of the kind of graph I am after.

How does one do this?

You can always use Manual Tick specifications:
ticks = Join[Range[-25, 25, 5], Range[20, -25, -5]];

ListLinePlot[data[[All, 2]],
