Anybody know of an easy method of swapping the x and y axes over on a scatter
graph.  ie so that the data graphed as the y-axis data becomes the x-axis and
vice versa.  I have data for two values of Q and one of P in a supply and
demand diagram.  The Q comes out on the vertical axis whereas an economist
requires P on the verical axis and Q on the horizontal.  There are two lines
that cross at equilibrium
