f[x_] := x^2-4x+4;

p1 = Plot[f[x], {x,-6,10}];

Show[p1 /. {x_, y_} :> {y,x}, 
    AspectRatio->GoldenRatio, ImageSize->178];

Plot[Evaluate[x /. Solve[y==f[x], x]], {y,0,f[10]}, 
    AspectRatio->GoldenRatio, ImageSize->178];

Needs["Graphics`ImplicitPlot`"];

ImplicitPlot[y==f[x], {y,0,f[10]}, 
    AspectRatio->GoldenRatio, ImageSize->178];

For a scatter plot go to the on-line help's master index and type scatter.  You
will be directed to ListPlot

Hello everyone,

	I'm new to Mathematica, so I hope you'll forgive my first couple of 
naive questions.

	I've used Plot to graph a parabola as follows: Plot[ax^2 - 2bx + c, 
{x, xMin, xMax}].  Is there any way to plot the function so that y 
appears on the horizontal axis and x on the vertical?  (I realize the 
parabola part is uninteresting; it's actually the solution to a 
standard problem in financial economics involving the minimization of 
investment portfolio risk for a given expected return.)

	Another plot-related question, if I may: do all plots require the 
specification of a domain as {x, xMin, xMax}?  For example, how would I 
create a scatter plot of experimental data where I have a long 
two-column list or matrix consisting of x and y observations where the 
data determine the domain and range?

	Sincerely,

		Gregory
