Estou tentando gerar um grupo de gráficos de barras com 3 figuras e concluí com sucesso e o resultado pode ser visto abaixo.
Problema: Quero os dois primeiros gráficos de barras (a e b) no mesmo estado, mas para o terceiro gráfico de barras ((c) perda Q e perda P), como posso incluir duas barras para cada rótulo no eixo X com uma legenda apenas para esse gráfico? Para reiterar, quero duas barras para 3-6, duas barras para 6-12 e duas barras para 12-24 com uma legenda exclusiva para o terceiro gráfico. Além disso, alguém pode me ajudar a reduzir o espaço entre os gráficos de barras (a,b,c)?

Alguém pode me ajudar com esse problema?
Obrigado!

- Aparentemente na primeira tentativa de responder a pergunta eu entendi mal...
- Aprendi com a bela resposta do @Torbjørn T., agora eu sei, que o principal problema é adicionar ao último diagrama P um conjunto de barras na cor azul.
- Isso pode ser relativamente fácil de fazer:
- Conjunto Q (na cor preta) de barras deslocadas com pequena quantidade para a esquerda
- adicione um novo conjunto de barras P (em azul) e desloque-o na mesma quantidade para a direita
- No novo MWE são preservados os estilos de diagrama da primeira versão da definição de resposta.
- Para padrões agora é usada
patterns.metaa biblioteca.

Pode exigir alguns ajustes extras, e coloquei a legenda acima do gráfico com entradas de espaço reservado. Na verdade, não há espaço dentro de um eixo para a legenda.
A principal mudança é usar ybarcomo opção to the groupplotem vez de to each \addplot, e usar deslocamentos manuais de barra para posicionar as barras corretamente.
horizontal sepnos group styleconjuntos o espaço entre os eixos.

As barras são criadas através de um
picelemento que depende de três argumentos (altura, rótulo e padrão de preenchimento).As dimensões são controladas como variáveis globais no início; você pode modificá-los como desejar.
