MINUSING 2 GRAPHS

[Moony]

Hi all !!!

Please help me. Attached I've sent my Labview programm. I need to minus XYGraph2 from XYGraph1. Please see, is my version is right????

THANKS IN ADVANCE SOOOOOOO MUCH! 

P.S. I know, my question seems very basic and elementary, but, please, be so kind and answer me.

It looks like you're correctly subtracting Graph 2 from Graph 1 and Plotting it in Graph 3 to me.

Are you expecting something different?

EDIT: Nevermind, I just ran it so it looks like subtracting cluster arrays may do something weird.

Hi Moony,

When you say you need to minus XYGraph 2 from XY Graph 1, do you mean that you need to subtract the variable (y) values, taken from graph 2, from the variable (y) values, taken from graph 1?

At the moment it appears you are taking values from both the constant (x) and variable (y) axis from each other, I believe this is why you are getting the vertical straight line at 0.00 on the constant axis.

Actually, it still looks good.

The smallest array will set the number of datapoints that you get.  Are you expecting the arrays to be the same size?

EDIT: And Dominic is right that you're squashing your X values.  I missed that.

Hi DominicRoberton and Taki1999!

Thanks for replies. About your question:

I mean that I need to subtract the variable (y) values, taken from graph 2, from the variable (y) values, taken from graph 1. I think I did something wrong, wasn't it???

Does this make any more sense?

DominicRoberton, 

My Labview version is 8.5, and your document I can't open...

Would you be kind to send me once more saving for my version?

Thank you in advance...

Please, answer my last question. To me is very fussy how can I get several graphs in one window...

Can you help me with this?

Best regards,
