Thanks Ben, I've stumbled upon time-ticks but initially discarded it as in the project I had in mind the data points need to be uniformly spaced not the time ticks (measurement is made based on other triggers irrelevant of discrete time - believe it or not it has its uses :) ) and time is used for ordering and for x labels. But your examples and pointing to time-ticks showed me some work with time-series which is good point to start with, so thank you. I will play with it but I think it is doable what I have in mind - plot seems to be quite mature.
