Problemas com margens na matriz tikz

Question

Estou fazendo um jogo de tabuleiro quadrado, que exige que o texto nas células seja girado (para que todos os jogadores possam lê-los). O problema que tenho é que ao girar a célula aparecem alguns espaços extras, que não consegui eliminar. Conforme sugerido em outras respostas neste site, usei

anchor=base,minimum width=1.75cm,minimum height=1.75cm,text height=2ex,text depth=0.25ex

e

column sep=0cm, row sep=0cm, outer sep=0pt,inner sep=0

onde pertence. Mas ainda recebo o erro. Meu código é:

Minha saída:

Como posso me livrar de todos os espaços em branco, para que a rotação não atrapalhe meu quadro?

Answer 1

uma solução para o problema básico é dada emSigur Comente. No entanto, seu código pode ser simplificado e torná-lo mais conciso:

• definindo estilos separadamente para cada coluna. com isto todos os comandos locais para rotação e muitos para cores tornam-se supérfluos
• é melhor definir o estilo dos nós em um só lugar, como opções dematrix
• uma vez que o conteúdo dos nós são números, a prescrição de text depthsupérfluos
• ser nós quadrados é suficiente para determinar o tamanho mínimo dos nós

mwe resultante é então:

Answer 2

Isenção de responsabilidade: crédito total para Sigur, que resolveu o problema. Tudo o que fiz foi fazer alguns pequenos ajustes adicionais. O principal problema é resolvido configurando anchor=center, conforme apontado por Sigur, caso contrário os centros de rotação não são os mesmos. As pequenas alterações estão marcadas no código.
