Stacked graphs are hard to compare to eachother. Eye-balling the height of middle veins of data is especially hard. Comparing a line graph is easier because the height you're estimated is the difference between values, and you already know which is absolutely larger. Two specific problems with your visualization are the margin between the veins and the fact that you scroll horizontally. This data is very much like tracking the active users on a service, with new, churned, retained, and resurrected users. I'm very familiar with that topic and think your visualization is bad for this data.
