我有一个由多个音频文件（每个人一个）的语音转录构成的数据帧：
# Name Start_Time Duration Transcript
# Person A 12:12:2018 12:12:00 3.5 Transcript from Person A
# Person B 12:12:2018 12:14:00 5.5 Transcript from Person B
# .........................

# Person N 12:12:2018 13:00:00 9.0 Transcript from Person N
有没有办法：
对于第2部分，每“ x”分钟的条形图的条形高度与“ n”个最常见的单词出现的总和成比例吗？有没有更直观的图形方式显示此信息的方法？
编辑： 我正在附上我现在拥有的基本的最小Ipython笔记本
问题：
