Well, I probably shouldn't say. Just trust me on this. You'll find out eventually when you get enough points. Thanks for moving though.

Well, I'll never get to your or Walter's stratospheric levels, so I'll not be holding my breath... :) But, I can't complain re: my treatment from TMW to date, in fact, I'm very grateful.
And being at point that "I no longer buy green bananas" is beginning to not be so far off, odds aren't necessarily in my favor... :)

Per IA's direction...with a correction for the data variables--dpb :)
You don't need two axes for that, just hold on
hold on
hSc(1)=scatter(xTrain,yTrain);
hSc(2)=scatter(xTest,yTest);
hL=plot([0 10],[0 10],'k-');
box on
legend(hSc,'Training','Testing')
with the other parameters of color, marker style, etc., etc., ... as you wish.

  1. Fit striaght line to the given data using polyfit.
  2. Plot the line using plot function.
  3. Use hold on
  4. Plot the given data using scatter.
  5. To put a legend use legend.
Also have a look on the function plotregression.

NB:
Re: 1. above, the line isn't the OLS fit of the data but the 1:1 45 of the input:output that would be the perfect correlation.
