Hi All,

I am using pds:-animate to show the results of integration of a two function system, u(x,t) and v (x,t). I would like this command uses two different colors for each line but the command "color=[blue, green]" is not working and both lines have the same color (blue).

Some help?

Thanks a lot,

Javier
