The convention I've used is that this is okay for line graphs like the ones that you've used, but not okay for bar graphs.

- gojomo 17y agoIt also depends on whether the main purpose of the graph is to show changes along the ranged axis (as if from period to period over time), or the magnitude of differences between the lines on the ranged axis. If the latter, a zero origin is fairer. While the day-to-day differences are of some interest here, the main interest is provider vs. provider, so the axes are not ideal. They make the provider-to-provider differences seem larger.
