Finding all points above a threshold

[ofithcheallaigh]

Hello,

I will say sorry in advance if this has been answered somewhere here (I did do a quick search).

I have a single column of data, and I am wondering how I can find the values all off the points about a specific level ...I then want to plot all those points.

Thanks in advance.
Seán
