我正在通過 .csv 文件導入數據并繪制它，但是當我繪制圖形并嘗試將其保存到我的谷歌驅動器時，它只保存一個沒有任何數據的空白圖像。我正在使用谷歌協作實驗室。這是我的代碼：#Displaying the Dataimport matplotlib.pyplot as pltimport numpy as npimport pandas as pdplt.title("Score of Each Raisan Thrown", fontsize ='x-large')plt.ylabel("Valid Raisans Thrown", fontsize='large')plt.xlabel("Score", fontsize= 'large')dart = data[:,0]score = data[:,1]plt.plot(score ,dart, marker='o', linestyle='none', color='black')ax = plt.subplot()ax.set_facecolor('seashell')# Adding ticks to make my plot easier to understand/readax.set_yticks([20,40,60,80,100,120,140,160,180,200])ax.set_xticks([-16,-14,-12,-10,-8,-6,-4,-2,0,2,4,6,8,10,12,14,-16])fig = plt.figure(figsize=(10,5))fig = plt.gcf()plt.draw()fig.savefig(datapath+'My Experiment1 Plot')plt.show()

因為你的
fig = plt.figure(figsize=(10,5))
fig = plt.gcf()
plt.draw()
fig.savefig(datapath+'My Experiment1 Plot')
出現在所有繪圖命令之后，這意味著您正在創建一個新圖形而不繪制任何內容并保存它。您需要重新排列命令：
# get the data:
dart = data[:,0]
score = data[:,1]
# set up the fig and axes:
fig, ax = plt.subplots(figsize=(10,5))
# plot the data
plt.plot(score ,dart, marker='o', linestyle='none', color='black')
# additional formatting
plt.title("Score of Each Raisan Thrown", fontsize ='x-large')
plt.ylabel("Valid Raisans Thrown", fontsize='large')
plt.xlabel("Score", fontsize= 'large')
# even more formatting
ax.set_facecolor('seashell')
# Adding ticks to make my plot easier to understand/read
ax.set_yticks([20,40,60,80,100,120,140,160,180,200])
ax.set_xticks([-16,-14,-12,-10,-8,-6,-4,-2,0,2,4,6,8,10,12,14,-16])
fig.savefig(datapath+'My Experiment1 Plot')
plt.show()
