Non-linear data selection [message #71002]

Hi All,

There is an interesting problem that I often come across.....
I have a scattered dataset of x and y, say 1000 elements each. The
data could be of any shape, for now, let's assume it is scattered
allover the X-Y window.

There is straight line (y=mx+b, could be some other curve as well)
that that crosses the plot, I need to select all data points this
line.
If it is just a one value for y, the WHERE statement is ok, but how to
do this?

Any help is greatly appreciated.
Thank you,
J
