matplotlibの - はAttributeError：不明なプロパティメーカー

Question

マイコード：

from matplotlib import pyplot as plt 
years = [1950, 1960, 1970, 1980, 1990, 2000, 2010] 
gdp = [300.2, 543.3, 1075.9, 286.5, 5979.6, 10289.7, 14958.3] 
plt.plot(years, gdp, color= 'green', maker='o', linestyle= 'solid') 
plt.title("Nominal GDP") 
plt.ylabel("Billions of $") 
plt.show() 

私は、Python 3.6.2でこのプログラムを実行していますが、私はエラーのすべての並べ替えを取得しています。以下は私が得ているエラーです

誰かが助けてもらえますか？ pl.plot()のmatplotlibのドキュメントから

Answer 1

：

marker: :mod: A valid marker style <matplotlib.markers>

だからあなたplot()コール
