How to make scatter

i want to make scatter but like this, how can i do this???

i want that graph is have two y axis and two x axis with same scale

in the picture I edited it using pain to add line on the top and right of the graph

i want to do this with matlab

thanks before and sorry for my bad english

[dpb]

You don't need two axes for that, just hold on

hold on
hSc(1)=scatter(xMeas,yMeas);
hSc(2)=scatter(xMeas,yMeas);
hL=plot([0 10],[0 10],'k-');

with the other parameters of color, marker style, etc., etc., ... as you wish.

I've used

hold on

but still not getting a line on the top and right of the graph

I want to make a graph like the left one not the right one

@dpb, again, put it as an official Answer so it can easily be seen and Anges can "thank" you by Accepting your answer and giving you reputation points (which has some benefits you may not be aware of).

What other benefits are associated with more reputation points after MVP status, IA? Besides the commemorative marker TMW sends annually, anyways... :)

I've really never paid much attention -- I followed the old cssm newsgroup and was reluctant to move over when TMW went to the forum instead...but it is my entertainment after retirement from the consulting gig so I'm still hanging around...I told myself then I'd suffer through enough to get to the 40-pt mark before I gave it up. I guess I kept that one, anyways.

[Image Analyst]

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.

[dpb]

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... :)

Answer 1

[dpb]

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.

Answer 2

[KSSV]

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.
