Joe, I gather that data is 2 boxed lists. The first box contains the day number and the second box contains a point in time between 0 and 24*60*60. The latter indicate when a step was taken. Furthermore, both boxes are numbers` in nondecreasing order. Right?
In place of your plot I am very tempted to break up the time points for each day into counts of equal intervals kind of like histograms are created and make a histogram/frequency distribution for each day, where the histogram bins are really time slots. My reason for not liking the plots is that the points are so close together in many regions that you cannot detect any distinctions between the various days. At http://jsoftware.com/help/dictionary/dicapdot.htm the histogram verb is quite effective at this, but seems to be overkill because your data seem to already be sorted.
