Hello

I have three vectors: X, Y, Z.

Each of them has size 16.

In X and Y i have "coordinates on the map" and in Z i have "terrain

height".

I wanted to draw it using meshz(X,Y,Z), but the problem was that i had

only very few points which described my terrain (only 18 points, and each

of them describe location and it's height). And i do not want to use "any

interpolation".

So i decided to draw it using 2D (for example plot) - i want to draw 18

dots and each dot's color should describe height (for example, if it's

higher it sould be more red).

Is there any function which could do it for me (like mesh), or i have to

do it by hand ?

Thanx for any help.

Michal

      Look at the SCATTER and SCATTER3 functions.
