当我绘图时，它显示TypeError:int（）参数必须是字符串、类字节对象或数字，而不是“tuple”

Question

我的准则：宏观经济学=pd.read_csv文件（r“C:\Users\champion\Desktop\哈哈\马克思经济学.csv", encoding=“big5”，skiprows=[0,1,2,3]，名称=[“年”，“行业”，“金钱”]）

data=macroeconomics[["industry","money"]].dropna()
year={"year":macroeconomics["year"]}
year_frame=DataFrame(year).dropna().drop_duplicates()
finish_year=year_frame.reindex(range(151),method="ffill")#handle data

total=pivoted["industry"]+pivoted["sevice_industry"]+pivoted["agruiculture"]
pivoted["agruiculture_ratio"]=pivoted["agruiculture"]/total
pivoted["industry_ratio"]=pivoted["industry"]/total
pivoted["sevice_industry_ratio"]=pivoted["sevice_industry"]/total

plt.figure((15,8))
pivoted["agruiculture"].plot()#I don't know why I can't plot.
pivoted["agruiculture_ratio"]
year
1981    0.059519
1982    0.062761
1983    0.060052
1984    0.053657
1985    0.050128

Answer 1

在matplotlib中设置figure size的正确方法是

plt.figure(figsize=(15,8))

将plt.figure((15,8))放进去，会让元组被解释为无法工作的图号。在
