SleepyHead Graph Scaling Issues (Outliers)
I have a question about the SleepyHead software: is there a way to filter out outlier data points so the daily graphs are scaled correctly?

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.

Screenshots are worth another 1,000 words:

RE: SleepyHead Graph Scaling Issues (Outliers)
I found and downloaded SleepyHead v0.9.4-1 (unstable, crash-prone), and that seems to fix both of my problems. The outlier datapoints are automatically thrown out, and also the graph scaling in the Preferences work too!

I noticed that when setting the min/max Y-scaling in the Preferences --> Graphs, you also have to UNcheck "Allow YAxis Scaling" under Preferences --> Appearance --> Other Visual Settings. This setting seems to only be available on the unstable build.
