polygon function

[<VINCENT_LEFOUEST@xxxxxxxxxx>]

Dear users,

 

I have a 3 columns ascii file with Longitude, Latitude, a SST value.

I would like to plot a symbol representing each georeferenced point and to associate to this symbol a color proportionnal to the SST value.

 

Can the polygon function do it?

 

Thank You in advance for your help.

 

Vincent
