// starting from scratch, we use the constructor that takes an existing axis and
// clones it (values in the superclass Axis only are cloned). PlotSurface2D
// automatically determines a suitable axis when we add plots to it (merging
// current requirements with old requirements), and we use this as our starting
// point. Because we didn't specify which Y Axis we are using when we added the
// above line plot (there is one on the left - YAxis1 and one on the right - YAxis2)
