Clipped Output Sine Wave Signal

A sine curve, where the y-values do not exceed a certain value.

PGFPlots has two different types of clipping: the first is the graphical clipping operation which is activated by clip, the second is based on coordinate value manipulation, more precisely by restrict y to domain*.
