Displaying two different waves on one x-axis simultaneously using axis break

I would like to display two different waves on the same x-axis with an axis break in between as shown in the attached picture (2 waves shown with different colours). Can someone set me on the right path on how to do this?

Thanks
You need the package called Split Axes. Plot out your two waves as you want them and then activate the package. Looks like you'd want to split 50% along the bottom axis.
