使用 matplotlib 和 pandas 制作 groupby 图
making groupby plot using matplotlib and pandas
我有一个代码可以将图形绘制成流线
代码是
import matplotlib.pyplot as plt
import pandas as pd
years=["ASD","MNG","KQR","MND","QST", "MNR"]
dataavail={
"Jan":[20,20,30,19,10,21],
"Feb":[20,13,10,18,15,30],
"Mar":[20,20,10,15,18,30],
"Apr":[20,20,10,15,18,0],
"May":[20,20,10,15,18,0],
"Jun":[20,20,10,15,18,0],
"Jul":[20,20,10,15,18,0],
"Aug":[20,20,10,15,18,45],
"Sep":[20,20,10,15,18,0],
"Oct":[20,20,10,15,18,0],
"Nov":[20,20,10,15,18,0],
"Dec":[20,20,0,0,0,0],
}
df_month = pd.DataFrame(dataavail, index=years)
fig, ax1 = plt.subplots(1, figsize=(8, 5))
df_month.plot(kind='bar', stacked=True, colormap=plt.cm.tab20, ax=ax1)
plt.legend(loc="upper right", ncol = 3,handlelength=1.5, borderpad=0.2, labelspacing=0.2)
plt.xticks(rotation=0)
plt.show()
但是,我需要 groupby 图而不是堆栈图,如图所示,其中 x 轴应与第一个 plot.can 任何人帮助我。
IIUC 你想要一个未堆叠的条形图吗?
df_month.plot.bar()
输出:
使用您的代码:
您应该删除 stacked=True
(或使用 stacked=False
):
df_month = pd.DataFrame(dataavail, index=years)
