Set Y-Intercept in Script

Hey again,

 

Trying to have my plot have the "Fit Line" go through 0.

 

I can't find it in the online documentation.

 

Cheers,


Tyler

Re: Set Y-Intercept in Script

You are in the right place (Fit Y by X -> Bivariate) but don't use Fit Line command. Use Fit Special. The dialog box will contain a control so that you can constrain the y-intercept = 0.

Learn it once, use it forever!

Re: Set Y-Intercept in Script

Thank you for your promt answer, I guess I should have been more explicit, sorry.

 

I am scripting a Bivariate Analysis for a large numner of chips and reticles and so need to set it to zero in the code:

 

E.g.,

 

BivAnalysis = Bivariate(

Y ( Eval(yparam)),

X( Eval(xparam)),

Fitline ( {Line Color()}),

);

 

Thanks for all the help!

Re: Set Y-Intercept in Script

There are two ways to figure this out.

 

1) Use Help->Scripting Index to look at the Bivariate object where you'll see all the messages it can take, including Fit Special.

2) Do it once interactively and then look at the script that JMP gives you to reproduce it.
