View outlier scatter plot

Here we create and display a scatter plot of the first and second principal components,

pcaginzu.plotPCvsPCWithOutliersInY(1,2)

Note: You might need to execute the command "show()" following the above statement in order to make the plot window appear. If you are using ipython in a UNIX-based operating system, you can optionally use "ipython -pylab" to make figures appear without the show() command. The Matplotlib http://matplotlib.sourceforge.net documentation has more information for interacting with plot windows, including zooming and panning within plots and saving the figure to files.
