I tried that too, but our activity graph's weight support is really not great, that's why I didn't really like it that much.
Without individual samples, every different stack looks like just 1 sample, even if its weight was 1000. So it really looks disproportionate and you really don't see the stacks with lots of weight that easily by just clicking around on the timeline.
