python使用scrt时间戳画图

scrt生成时间戳

SecureCRT 日志添加时间戳(精确到毫秒)
[%h-%m-%s.%t] 其中 %t 表示毫秒
设置以及效果截图如下：

python使用时间戳画图

代码

'''
python帧间隔绘图脚本使用：
1.首先需要安装Anaconda3(python是3+版本)
2.然后添加环境变量
3.然后cd 到Anaconda3安装目录，我的是C:\ProgramData\Anaconda3
4.使用方式C:\ProgramData\Anaconda3>python C:\Users\tsh\Desktop\drawByFramejitter.py   C:\Users\tsh\Desktop\drawByFramejitter.log 
PS：1.这里python用的不是自己安装的版本，是C:\ProgramData\Anaconda3目录下的python工具
    2.session用的是scrt添加的时间戳
