Hello everybody,

I have a problem and I think that it should be easy to solve but for some reason I do not manage that.

I have arrays containig latitude, longitude and concentration values.
I wanna plot the concentration values at the corresponding lat/lon point in different colours for different concentration values. And all that on a worldmap (or a part of it).

Any ideas?

Cheers,
Nanami

plot3k (http://www.mathworks.com/matlabcentral/fileexchange/9519) does
what you want in XY space. I don't imagine it would be too difficult for
you to modify it to work in lat/lon space :-)

If you have Mapping Toolbox, use AXESM, PLOTM, and SCATTERM in combination.

If you don't, AXES, PLOT, and SCATTER may do but keep in mind those plot on
a flat axes, not an axes specifically designed to hold a map in a specific
map projection.
