熊猫条形图轴

Question

我正在建立下面的链接图，我需要将属于数据顺序的x轴更改为CCAA或城市。我该怎么做？谢谢！

data = data.sort_values(by=['Cases'], ascending=False)

Combined = data2[['Cases','Deaths','Recovered']].plot(kind='bar',[enter image description here][1] figsize=(10, 10), legend=True, fontsize=13 )
plt.show

Data

Answer 1

指定xticks

data2[['Cases','Deaths','Recovered']].plot(
        kind='bar', figsize=(10, 10),
        legend=True, fontsize=13, 
        xticks=data2.CCAA)

Answer 2

在绘制前将列CCAA转换为索引：

(data2.set_index('CCAA')[['Cases','Deaths','Recovered']]
      .plot(kind='bar', 
            figsize=(10, 10), 
            legend=True, 
            fontsize=13))
