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
