Eu tenho esse pgplot com gráficos const. A ideia é que a primeira área a NW (que na verdade é o fundo) seja totalmente verde. Então a segunda área deverá ser azul e a terceira branca. Como vocês podem ver há algum ruído no preenchimento que utiliza a cor de fundo verde na área azul... Não vejo o que pode estar acontecendo. Eu apreciaria qualquer ajuda!
Adiciono abaixo a figura e o código que estou usando.

Na verdade, seu código produz um erro quando compilado. Existem outros erros também, que você pode ver na pequena caixa vermelha com o número 13, ao lado do botão de recompilação. Os erros sempre devem ser corrigidos se aparecerem (clique no 13 para mais informações), caso contrário você não poderá confiar na saída.
Dito isto, você simplesmente esqueceu de remover a ;após o fechamento }da lista de coordenadas do primeiro gráfico, então você tem
}; %<--- this semicolon must be removed
\closedcycle;
Remova o ponto e vírgula e parece funcionar bem.
