How do I visually represent points on a graph?

Hi, I have data from 10 wave probes situated around a tank. I have found the percentage change at each of these probes for various wave buoys layouts within the tank and was wondering whether it is possible to represent these on a surface in matlab?

i've tried using surf but it says my z(%change) needs to be a matrix not a vector or scalar

the location of each probe is:

 x=
8500
8500
9800
9800
11800
11800
13800
13800
16800
16800

 y=
1000
-1000
-1750
-3750
-1750
-3750
-1750
-3750
1000
-1000

 %change=
1.98699625630532
5.10041883616840
-8.47874954187543
-4.08563792135973
7.71330184023595
8.78867861058347
-14.9605802234170
-3.17825963425018
-20.6789076505716
-12.7915246561184

I would like to represent the position of the probe on a surface as a circle with its colour denoting the %change whereby 0=yellow negative=red positive=green

is this possible??

thank you

If you want points:

 plot3();

If you want a surface, you'd need to interpolate.

 scatteredInterpolant()

ive been playing and what i basically want is scatter(x,y,60,jet(%change),'filled') but cant seem to make the colour of the circles match %change

 scatter(x,y,60,change,'filled');
 colormap('jet');
