熊貓情節指數超出界限但指數長度相等

我試圖繪製從我的熊貓DF，沿y軸索引x軸作爲一般散點圖的時間，但即使值I希望繪製都是相同的長度，我收到以下錯誤：熊貓情節指數超出界限但指數長度相等

raise IndexError("indices are out-of-bounds") 
IndexError: indices are out-of-bounds

繪製指數（沿x軸）的代碼和在y軸上的時間差異如下：

fig = plt.figure() 
ax = fig.add_axes([.1,.35,.6,.6]) 
ax=df.plot(ax=fig.gca(),kind='scatter',x=df.index, y=df.timediff, color='red', edgecolors='black') 
plt.show()

df.timediff列的格式如下：

0 1970-01-01 00:19:14 
1 1970-01-01 00:19:53 
2 1970-01-01 00:23:50 
Name: orb_timediff, dtype: datetime64[ns]

，並從輸出：

print(len(df.timediff)) 
print(len(df.index)) 
>> 
291 
291

完整的跟蹤堆棧低於：

您可以包括完整的堆棧跟蹤？ –

有問題，需要兩列數字。

所以可能的解決方案是通過dt.total_seconds轉換to_timedelta然後seconds：

df['orb_timediff'] = pd.to_timedelta(df['orb_timediff']).dt.total_seconds().astype(int) 
df = df.reset_index() 
print (df) 
    index orb_timediff 
0  0   1154 
1  1   1193 
2  2   1430 

fig = plt.figure() 
ax = fig.add_axes([.1,.35,.6,.6]) 
ax=df.plot(ax=fig.gca(), 
      kind='scatter', 
      x='index', 
      y='orb_timediff', 
      color='red', 
      edgecolors='black') 
plt.show()
