Try adding in 10000 to the points option.
This little flow I played with and you will see the data rolloff the chart as new data comes in once it hits the time limit.
It looks to me that if the count is greater than the number of points that would show in the time limit, only the number of points that fit in the time limit will show and new points will roll off the older points.
