Voc\u00ea pode usar a seguinte fun\u00e7\u00e3o para exibir valores em um gr\u00e1fico de barras marinho<\/a> :<\/span><\/p>\n

 Esta fun\u00e7\u00e3o funciona para gr\u00e1ficos de barras horizontais e verticais.<\/span><\/p>\n
 Os exemplos a seguir mostram como usar esta fun\u00e7\u00e3o na pr\u00e1tica com o conjunto de dados \u201cdicas\u201d da Seaborn:<\/span><\/p>\n
 import<\/span> seaborn as<\/span> sns<\/span>\nimport<\/span> pandas as<\/span> pd<\/span>\nimport<\/span> numpy as<\/span> np<\/span>\n\n#load tips dataset<\/span>\ndata = sns. load_dataset<\/span> (\u201c tips<\/span> \u201d)<\/span>\n\n#view first five rows<\/span>\ndata. head<\/span> ()\n\n\ttotal_bill tip sex smoker day time size\n0 16.99 1.01 Female No Sun Dinner 2\n1 10.34 1.66 Male No Sun Dinner 3\n2 21.01 3.50 Male No Sun Dinner 3\n3 23.68 3.31 Male No Sun Dinner 2\n4 24.59 3.61 Female No Sun Dinner 4<\/span>\n<\/span><\/strong><\/pre>\n
 Exemplo 1: Exibir valores em um gr\u00e1fico de barras vertical<\/strong><\/span><\/h3>\n
 O c\u00f3digo a seguir mostra como exibir valores em um gr\u00e1fico de barras vertical:<\/span> <\/p>\n
 #create vertical barplot<\/span>\np = sns. barplot<\/span> (x=\" day<\/span> \", y=\" tip<\/span> \", data=data, ci= None<\/span> )\n\n#show values on barplot\n<\/span>show_values(p)\n<\/strong><\/pre>\n
\"\"<\/p>\n
 Exemplo 2: Exibir valores em um gr\u00e1fico de barras horizontal<\/strong><\/span><\/h3>\n
 O c\u00f3digo a seguir mostra como exibir valores em um gr\u00e1fico de barras horizontal:<\/span> <\/p>\n
 #create horizontal barplot<\/span>\np = sns. barplot<\/span> (x=\" tip<\/span> \", y=\" day<\/span> \", data=data, ci= None<\/span> )\n\n#show values on barplot<\/span>\nshow_values(p, \" h<\/span> \", space= 0<\/span> )\n<\/strong><\/pre>\n
\"\"<\/p>\n
 Observe que quanto maior o valor usado para espa\u00e7o, mais distantes os r\u00f3tulos estar\u00e3o das barras.<\/span><\/p>\n
 Por exemplo, vamos alterar o espa\u00e7o de 0<\/strong> para .05<\/strong> :<\/span> <\/p>\n
 #create horizontal barplot<\/span>\np = sns. barplot<\/span> (x=\" tip<\/span> \", y=\" day<\/span> \", data=data, ci= None<\/span> )\n\n#show values on barplot<\/span>\nshow_values(p, \" h<\/span> \", space= 0.05<\/span> )<\/strong> <\/pre>\n
\"\"<\/p>\n
 Nota<\/strong> : Para alterar o n\u00famero de casas decimais exibidas, basta alterar o valor nesta linha da fun\u00e7\u00e3o:<\/span><\/p>\n
 value = ' {:.1f}<\/span> '. format<\/span> (e.g. get_height<\/span> ())\n<\/strong><\/pre>\n
 Por exemplo, altere-o para . 1f<\/strong> a .2f<\/strong> para exibir duas casas decimais em vez de uma.<\/span><\/p>\n
