Hi everyone,

I indeed have been working with irregular data grids. I have  
represented the data using polygon features coloured depending the  
value.
The main problem is that you have to draw every feature independently,  
so your algorithm grows rapidly with the size of the data (ni*nj) and  
gets quickly slow. What is the size of the grid you plan to draw ?
