Curve/Funcfit over range of scaled x data instead of point numbers

Thu, 03/08/2012 - 04:33 pm

Is there a way to specify the curvefit range in terms of the wave scaling, versus using just the point numbers?

Yes. Here is an example:

Make data = sin(x/8) + gnoise(.1)

SetScale x, 0, 1, "", data

Display data

CurveFit sin data(.2,.4) /D 

ModifyGraph rgb(fit_data)=(1,12815,52428)

This is explained in Parameters section of the the help for the CurveFit operation, third paragraph.

Thanks, I am not sure what I was doing wrong. Might have been brackets versus parentheses. Works great now!
