我試圖將我的步驟繪制為散點(diǎn)圖，然后最終添加一條趨勢線。我設(shè)法讓它與 df.plot() 一起使用，但它是一個(gè)折線圖。以下是我嘗試過的代碼：import pandas as pdimport matplotlib.pyplot as pltimport numpy as npdata_file = pd.read_csv('CSV/stepsgyro.csv')# print(data_file.head())# put in the correct data typesdata_file = data_file.astype({"steps": int})pd.to_datetime(data_file['date'])# makes the date definitely the index at the bottomdata_file.set_index(['date'], inplace=True)# sorts the data frame by the indexdata_file.sort_values(by=['date'], inplace=True, ascending=True)# data_file.columns.values[1] = 'date'# plot the raw steps data# data_file.plot()plt.scatter(data_file.date, data_file.steps)plt.title('Daily Steps')plt.grid(alpha=0.3)plt.show()plt.close('all')# plot the cumulative steps datadata_file = data_file.cumsum()data_file.plot()plt.title('Cumulative Daily Steps')plt.grid(alpha=0.3)plt.show()plt.close('all')這是它在我的 IDE 上的樣子的屏幕截圖：
