I AM helping you. But a vector is not obviously
an array of data in any specific form. You need
to explain what you have, else I'm just guessing.
And those wires on the mindreading thingy keep
shorting out on me. (It hurts like hell then.) On
the other hand, its just like electroshock therapy.
I've quit smoking, and I'm now down to only two
personalities. ;-)

Still not terribly clear. Why must I drag it out
of you?

Assuming that you have scattered data, then
you must use either griddata or my own gridfit
from the file exchange to convert it to a gridded
array. Then use contourf.
