interpreting histogram format #34

Open niyue opened 2 years ago

Thanks for creating such a tool, and I find it very useful when troubleshooting IO issues during development (under both Linux and macOS).

Could you please add some documentation explaining how to interpret the histogram format output? Initially I assume it represents a visualization of -json -pps but since histogram is 2D, I have some difficulty interpreting it.
