Changes

'''Advanced users ''' may set Y-Axis over-ride on many of the other charts as well. This increases user friendliness and read-ability. Otherwise, outlier data can re-scale the chart, causing irregular display of the main data and confusing day to day comparisons. The increments of Y-Axis may also end up in strange divisions. On the included examples, most of the Y-Axis have been overidden overridden to give a repeatable and consistant consistent view of each metric. A couple Y-axis overrides that increase usefulness are, '''leak rate''' 0-50 with dotted line at leak threshhold threshold and '''tidal volume''' 0-1000. '''Mask Pressure''' & '''Pressure''' can benefit from overide by setting to a tighter range around your own specific pressures. Try make all Y-Axis increments equal whole numbers. A dotted line at max mask pressure can be handy if using APAP. Finally, but maybe most helpful for interpreting your data, is to create at least 2 '''profiles'''. The first one I call 'compact' and the other 'detailed'. In the compact profile, shrink the height of as many data rows as possible. Size the flowrate graph so the spike ups are not too prominent, but the biggest are still easily seen. This will give you a good general picture of a nights therapy. This view however, will not be best for analyzing breath shapes and fine tuning therapy settings. For this you will want a profile you can switch too quickly with a couple of critical changes to at least '''Flow Rate''' and '''Mask Pressure'''. In order to set these, you should make sure the y-axis override is not too far off the actual flow rate and your pressure range. Fill the graph with the signal trace. Pick the best section of one of your best nights. Zoom in with left click till the max zoom is reached. From here drag the row height so that each breath is close to a semi circle, without being too tall or too squat. Roughly match the mask pressures to the same height as each breath shape, so they are relative to each other. You have now set a baseline target for your good breath shapes and a detailed view of the interaction with your machine. When looking at flow limitations or some other anomaly, you will have a much better idea of how severe or not, they actually are. Without this baseline and zoom, breaths can appear far worse or better than they actually are all dependent on the height your row display is. Drag some up and down and you will see!
