If you want to make a chart about the fluctuations themselves, another way would be to show the differences on chart with a centerline at zero and bars that go positive and negative. Or if you really want the cumulative then normalize the first or last data point to be zero.
The problem that people have with not starting at zero is how arbitrary it is. You can tell a completely different story depending on where you choose the starting point. So there should be some kind of justification for the chosen Y range.

It's always something that a graph maker should be thinking about for sure, and a blanket "anchor it at zero" is neither desirable, nor even necessarily possible all the time.
