From e-mail support requests:
I'm in need of a macro command that will delete the very first point of a
plot. I've got a situation where I have to use the "operate on Y" as this
Y=Y/X but my first point in X is zero...thus I end up with a divide by zero
error. Is there a way to delete this first point in the data (i.e. the X=0
point) so that I can go ahead and use the Y=Y/X command?
EditTruncate(some very small positive value,some very large positive
value)
This:
EditTruncate(1.E-100,1.E+100)
should work unless you're dealing with very large or very small numbers.

I also need to be able to delete all points with negative y values using a macro...is this possible? I've been doing it manually with "delete points
in a box" but I'm wondering if there is a better way via macro.
ClipY(0,1.E+100)
If you don't want the clipped parts connected, use
YCutoff(1,0,1.E+100)
This will preserve those points with negative Y values but not draw line segments to/from them.
