Graças a esta pergunta feita anteriormenteComo conectar imagens com setas em Latex?
Consegui criar um conjunto de imagens conectadas por setas. No entanto, tenho duas perguntas:
- como rotulo cada uma das imagens (para fazer referência no texto, por exemplo, à figura 1.2 ou 1.5)
- por alguns motivos, a imagem gerada preenche toda a página (visualmente é mais de meia página) ou, pelo menos, nenhum texto é permitido na mesma página da imagem. Alguma idéia de como corrigir esse problema?
obrigado

Se você quiser continuar com um matrix, poderá simplificar as coisas. Primeiro, eu usaria a opção matrix of nodes(você precisa carregar a matrixbiblioteca para isso), o que torna muito mais fácil estilizar os nós da matriz.
Então, você pode definir os rótulos automaticamente usando o figurecontador atual (e adicionando 1 a ele, porque ele só é atualizado depois de \captiondigitado) e anexar a ele o argumento fornecido por meio do seu lablumestilo.
Observe que já é possível fazer referência a nós de matrizes usando nomes de nós específicos, por exemplo, o primeiro nó no canto superior esquerdo da sua matriz seria mat-1-1, então você não precisa definir seus próprios nomes de nós, mas como deseja coloque as subfiguras de maneira boustrofedônica, mantive do seu jeito.
Quanto ao seu problema de a figura preencher a página inteira: provavelmente se deve ao tamanho das subfiguras. Tente escalá-los um pouco. O exemplo abaixo mostra que a figura deve ser colocada em uma página com texto, se isso for possível:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{matrix}
\usepackage{lipsum}
\begin{document}

\draw[marr] ([xshift=1mm]img-2.south east) coordinate (aux)

\draw[marr] (img-3) -- (img-4);
\draw[marr] ([xshift=-1mm]img-4.south west) coordinate (aux)

\draw[marr] (img-5) -- (img-6);
\end{tikzpicture}

Você pode deixar TikZ/PGF também calcula os rótulos de forma totalmente automática para você (você só precisa informar de alguma forma a contagem de colunas com antecedência):
\documentclass{article}

A referência é provavelmente mais fácil usando o subcaptionpacote, mas você sempre pode criar seus próprios contadores de referência (criei uma macro \refsetcounterbaseada, \refstepcountermas em vez de aumentar o contador, configure-o para um valor específico que é útil aqui):
\documentclass{article}

Na verdade, não tenho certeza do que você está procurando. Se você quiser manter a rotulagem e as legendas personalizáveis, talvez algo assim funcione:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{matrix}
\newcounter{matrix}
\newcounter{matrixnode}[matrix]
\renewcommand*{\thematrixnode}{\thematrix.\arabic{matrixnode}}

Adicionei alguns estilos para fazer com que as células da matriz tenham o mesmo tamanho. Para deixar isso mais claro, adicionei um pouco de cor aos nós para mostrar, que você pode simplesmente remover (excluindo fill=red!10).
Finalmente, as coisas podem ser muito mais fáceis usando o subcaptionpacote, no entanto, você não conseguirá posicionar os nós livremente (por exemplo, da direita para a esquerda):
\documentclass{article}
