No, not like that (although it does show a trend over time). And the numbers only show a cumulative total over time.
I have totalled the numbers per separate quarter. If there would be a bar for each quarter of each continent separately (and each continent would have it's own coloured bars), and all the subsequent quarters would be aligned on the horizontal line/axis, it would give you a different/better view, I think.
By the way, same could be done per month instead of per quarter.
Something like this post from jvonvokel ?
