在plotly python中將圖例顯示為條形圖的x軸標簽

Question

我正在繪制一個組條形圖，其中我在條形圖中映射了多行。 這是解釋我所做的事情的代碼：

data = [{"Project":"Project A","Features":{"AC":95,"Elec":130, "Area":2349.46, "Cars":30, "Rent":2345.00},"ScaledFeatures":{"AC":95,"Elec":130, "Area":2349.46, "Cars":30, "Rent":2345.00}},
{"Project":"Project B","Features":{"AC":95,"Elec":130, "Area":2120.00, "Cars":42, "Rent":5432},"ScaledFeatures":{"AC":95,"Elec":130, "Area":2120.00, "Cars":42, "Rent":2345}}
       ]
featureKeys = list(data[0]["Features"].keys())

for key in featureKeys:
    featureData = ([d["ScaledFeatures"][key] for d in data])
    minimumFeatureValue = min(featureData)
    for d in data:
        d["ScaledFeatures"][key] = d["ScaledFeatures"][key]/minimumFeatureValue

barData = []
for d in data:
    barData.append(go.Bar(name=d['Project'], x=featureKeys, y=list(d["ScaledFeatures"].values()),text=list(d["Features"].values()),textposition='auto'))

# set plot layout  
layout = go.Layout(
    xaxis={"mirror" : "allticks", 'side': 'top'} # x-axis also at top
)

fig = go.Figure(data=barData,layout=layout)

# Change the bar mode
#fig.update_traces(textposition='outside')
fig.update_layout(barmode='group')
fig.show()

這是它生成的輸出：

我想從中生成以下類似輸出，其中圖例在 x 軸中出現：

到目前為止，我所做的是使用多個軸，但這會在同一圖表中繪制自己的條形圖。 任何幫助表示贊賞！

您可以在此處使用多類別 x 軸，如本例所示。 但是，您會將 A/B 和 AC/Elec 等放在同一側。 如果您不想使用它，您可以使用注釋https://plot.ly/python/text-and-annotations/#simple-annotation 。 另外，在這里您可以考慮使用px.bar的plotly.express ： https : plotly.express
