原始數據Touch Time        Install Time3/28/2019 14:06  3/28/2019 15:343/27/2019 19:23  3/28/2019 15:223/28/2019 15:01  3/28/2019 15:183/28/2019 12:41  3/28/2019 15:183/27/2019 12:10  3/28/2019 15:08在此之后，我使用 read_csv 讀取了 csv 并創建了一個新的列差異df['diff'] =  pd.to_datetime(df['Install Time']) - pd.to_datetime(df['Touch Time'])這會創建一個列差異：      Touch Time     Install Time          diff0   3/28/2019 14:06  3/28/2019 15:34    0 days 01:28:001   3/27/2019 19:23  3/28/2019 15:22    0 days 19:59:002   3/28/2019 15:01  3/28/2019 15:18    0 days 00:17:003   3/28/2019 12:41  3/28/2019 15:18    0 days 02:37:004   3/27/2019 12:10  3/28/2019 15:08    1 days 02:58:00對于我的分析，我想將 diff 列中的值轉換為小時，然后使用 matplotlib 繪制它。我希望最終數據如下所示：0 days 01:28:00 should reflect as 1 1 days 02:58:00 should reflect as 26
