The upper section shows a jet narrowing from the nozzle and forming droplets along a horizontal distance scale. The lower plot uses x in micrometres from 0 to 750 and time in milliseconds from 0 to 90. The jet remains continuous to about 340 micrometres, then breaks into repeated droplet regions from about 350 to 750 micrometres.
