This command prints disk reads/writes per process every second:
iotop -bot > my.log
The output is like this:
11:19:25 Total DISK READ : 0.00 B/s | Total DISK WRITE : 198.47 K/s
11:19:25 Actual DISK READ: 0.00 B/s | Actual DISK WRITE: 339.69 K/s

I need a tool that takes this log file, and generates a chart that shows how reads/second evolved.
Requirements:
- Free
- Runs on Linux
