It's in nano-second unit, right? If so, it's very unconvenient for user to specify. Maybe we could support to parse unit (s, ms, us, ...) also. > +--io-merge-dist:: > + Merge events that are merge-dist nanoseconds apart. > + Reduces number of figures on the SVG and makes it more render-friendly. > + Default value is 1us.
