There are two variants of perf timechart:

of an arbitrary workload. By default timechart records only scheduler
and CPU events (task switches, running times, CPU power states, etc),

that can be viewed with popular SVG viewers such as 'Inkscape'. Depending
on the events in the perf.data file, timechart will contain scheduler/cpu
events or IO events.
In IO mode, every bar has two charts: upper and lower.
Upper bar shows incoming events (disk reads, ingress network packets).
Lower bar shows outgoing events (disk writes, egress network packets).
There are also poll bars which show how much time application spent
in poll/epoll/select syscalls.

--io-skip-eagain::
Don't draw EAGAIN IO events.
--io-min-time=<nsecs>::
Draw small events as if they lasted min-time. Useful when you need
to see very small and fast IO. It's possible to specify ms or us
suffix to specify time in milliseconds or microseconds.
Default value is 1ms.
--io-merge-dist=<nsecs>::
Merge events that are merge-dist nanoseconds apart.
Reduces number of figures on the SVG and makes it more render-friendly.
