how to match two curves?

[stephenzhou74]

Hello，

I have two curves. They have the same shape.

See attached file curve1.txt and curve2.txt, these two curves have different length.

For the curve2, if I manually multiply X by 0.017, multiply Y by 0.22, then curve2 will agree well with curve 1.

Is there a way in labview to find out these coefficients by curve fitting etc.?

Thanks a lot!

Take a look at the curve fitting vi's in LV.   Also open your  "find examples" for and search for  "fitting"  There are several basic examples that demonstrate fitting.
