Hi, I'm trying to generate a contour plot from a data set I have in Excel
showing how a given set of three of the 8 columns/categories are related to
each other. I pulled out three arbitrary columns using the subset function,
but I'm kinda lost with what to do from there.
Lets say I have this subset:
x y z
-------------------------
7 6 5.3
1 3.14 4.0
5 2.7 6.1
How would I plot a contour graph of the subset? Is that even possible?
Thanks.
