Re: Problems with Value2dDisplay

[James Marshall]

Hi,
  problem solved now, and I'm sorry to report it was down to a simple 
logical error in my code (of course!), in which I gave the wrong 
Discrete2D grid to the Value2DDisplay. Took me a while to realise 
because of the similarity of the data contained in both grids, which 
gave the same macro pattern as each other. Apologies, and thanks for 
the help,
        James
