Apparently out of the millions of data points, I will get a ridiculous outlier that causes the graph to scale to make the normal data points impossible to see. For example, last night I had a single EPAP datapoint of 329 H2O which is used as the maximum for graph scaling purposes.
Is this a bug with no way to work around?
BTW: I have gone into Preferences and set the Maximum Y-Axis values appropriately, but that doesn't seem to have an effect.
