step

The step function looks useful

 

hogi_1-1693555860881.png

 

some things which I noticed:

 

1) Don't use string values  as yi - although it seems to be "allowed":

2) Description - add-on:
Returns the yi argument corresponding to the largest xi which satisfies xi less than or equal to the x argument

- but only: IF there is another xi that is larger than x.

 

3) None of the yi values must be empty.

Re: step

I think JMP Help's Scripting Guide gives much better idea of the function than scripting index

Re: step

Interesting.  Step() seems to always choose the first string option, if one is given.

Show( Step( 500, 0, 1, 90, 2, 140, 3, 1000, "max" ) );	//"max"
Show( Step( 500, 0, 1, 90, 2, 140, "high", 1000, "max" ) );	//"high"
Show( Step( 500, 0, 1, 90, "mid", 140, 3, 1000, "max" ) );	//"mid"
