特定列的不同值的不同颜色
different color for different value of a specific column
我有这个数据框：

我想绘制 :
pivotD["close-open"].plot(figsize=(30,7),title="titolo",kind='bar')
用不同的颜色排列 ASKBID 的值。可能吗？
提前致谢
使用color参数：
colors = pivotD['ASKBID'].replace({np.nan: 'blue', 'BID': 'red', 'ASK': 'green'})
pivotD['close-open'].plot(figsize=(30,7), title='titolo', kind='bar', color=colors)
plt.show()
