Voc\u00ea pode usar a seguinte sintaxe b\u00e1sica para alterar a cor das barras em um gr\u00e1fico de barras empilhadas no ggplot2:<\/span><\/p>\n

 #create stacked bar chart\n<\/span>ggplot(df, aes(x=x_var, y=y_var, fill=fill_var)) + \n  geom_bar(position=' stack<\/span> ', stat=' identity<\/span> ') +\n  scale_fill_manual(values=c(' red<\/span> ', ' purple<\/span> ', ' pink<\/span> ', ...))<\/strong><\/pre>\n
 O exemplo a seguir mostra como usar essa sintaxe na pr\u00e1tica.<\/span><\/p>\n
 Exemplo: alterar a cor das barras no gr\u00e1fico de barras empilhadas no ggplot2<\/strong><\/span><\/h2>\n
 Suponha que temos o seguinte quadro de dados em R que mostra os pontos marcados por diferentes jogadores de basquete:<\/span><\/p>\n
 #create data frame\ndf <- data. frame<\/span> (team=c('A', 'A', 'A', 'B', 'B', 'B', 'C', 'C', 'C'),\n                 position=c('G', 'F', 'C', 'G', 'F', 'C', 'G', 'F', 'C'),\n                 points=c(22, 12, 10, 30, 12, 17, 28, 23, 20))\n\n#view data frame\ndf\n\n  team position points\n1 AG 22\n2 AF12\n3 AC 10\n4 BG 30\n5 BF 12\n6 BC 17\n7 GC 28\n8 CF 23\n9 CC 20<\/span><\/span><\/strong><\/pre>\n
 Se criarmos um gr\u00e1fico de barras empilhadas para visualizar os pontos marcados pelos jogadores de cada equipe, o ggplot2 usar\u00e1 um conjunto padr\u00e3o de cores<\/a> para preencher as barras:<\/span> <\/p>\n
 library<\/span> (ggplot2)\n\n#create stacked bar chart\n<\/span>ggplot(df, aes(x=team, y=points, fill=position)) + \n  geom_bar(position=' stack<\/span> ', stat=' identity<\/span> ')<\/strong> <\/pre>\n
\"\"<\/p>\n
 No entanto, podemos usar o argumento scale_fill_manual()<\/strong> para especificar as cores exatas que o ggplot2 deve usar para as barras:<\/span> <\/p>\n
 library<\/span> (ggplot2)\n\n#create stacked bar chart with custom colors\n<\/span>ggplot(df, aes(x=team, y=points, fill=position)) + \n  geom_bar(position=' stack<\/span> ', stat=' identity<\/span> ') +\n  scale_fill_manual(values=c(' red<\/span> ', ' purple<\/span> ', ' pink<\/span> '))<\/strong> <\/pre>\n
\"\"<\/p>\n
 As barras agora t\u00eam as cores exatas (em ordem de cima para baixo) que especificamos na fun\u00e7\u00e3o scale_fill_manual()<\/b> .<\/span><\/p>\n
 Observe tamb\u00e9m que podemos usar c\u00f3digos de cores hexadecimais na fun\u00e7\u00e3o scale_fill_manual()<\/strong> :<\/span> <\/p>\n
 library<\/span> (ggplot2)\n\n#create stacked bar chart with custom hex color codes\n<\/span>ggplot(df, aes(x=team, y=points, fill=position)) + \n  geom_bar(position=' stack<\/span> ', stat=' identity<\/span> ') +\n  scale_fill_manual(values=c(' #2596BE<\/span> ', ' #8225BE<\/span> ', ' #D4C443<\/span> '))<\/strong> <\/pre>\n
\"\"<\/p>\n
 As barras agora possuem os c\u00f3digos de cores hexadecimais que especificamos.<\/span><\/p>\n
