Is somebody who is given 10 tasks, which only take 5 minutes to complete, more product than somebody who is given 1 task which takes 50 mintues to complete? According to your chart the answer would be yes as the first person will have 9 more data points for a particular hour slot.
Anyway to create the chart you need to assign as x value for each unique name and then plot a series for each person. The horizontal axis labels are provided by a dummy series plotted on the secondary axis as column chart.
