[英]Is there a way to optimize this code for subplots in python?
我編寫了一個代碼,在按月匯總的數據中為每年的 .net 創建 8 個子圖。 我嘗試使用兩個 for 循環優化代碼,但我不知道如何將查詢部分集中在 pd df 中。 有沒有辦法以更好的方式重寫它或優化這段長代碼?
VF_data 只是一個 pandas dataframe,具有每年每月匯總的數字正值和負值。 其他列是月、年、日期。
謝謝大家!!

您可以遍歷.groupby("YEAR")
下面是一些例子:
df = pd.DataFrame({
"YEAR": ["2022", "2022", "2023", "2023"],
"x":[1, 2, 3, 4],
"y": [1, 2, 3, 4]
})
for i, (year, gr) in enumerate(df.groupby("YEAR")):
plt.subplot(1, 2, i+1)
plt.plot(gr["x"], gr["y"])
