Hi Marks,
ListPlot[data /. {x_,y_} -> {x, y^2}]
should works
Question:
=========
Hello all,
I have a data file called data.txt. It consists of 2 columns of
data. I am able to read with
data = ReadList["/home/mark/data.txt", {Real, Real}]; I let the first
column represent x and the second represent y. Then I plot y vs. x
with ListPlot[data]. My problem is that I need to plot y^2 vs. x.
So, how can I square all the y terms?
regards
mark
