(Bug) CPAP Graphs not showing data values with time drift
Issue: When hovering the cursor over any of the CPAP-based graphs, if the clock drift is enabled, OSCAR doesn't show the data value. For example, if you set the clock an hour ahead, the first hour of every single session will display 0 for the CPAP-based graphs. Similarly, if you set the clock backwards by -30 minutes, the last half hour of the graph also will display zero. It works as expected when drift is not enabled and the SpO2 charts work fine either way.
In the image above, the red line marks the point that corresponds to the size of the clock drift. In the top pair of graphs, you can see that only the SpO2 chart shows a value, whereas the Tidal Volume says 0. On the bottom example, on the right of the red line, you can see that both the SpO2 and the Tidal Volume show the correct values. This was with the clock drift set to +1 hour.
Expected behaviour: The value of the graph under the mouse cursor should be displayed at the top left of the graph strip for the whole chart, even when the CPAP Clock Drift is in use.
How to replicate:
1) Open an OSCAR profile and go to the Daily tab.
2) In preferences, ensure that the drift is set forward by an hour.
3) Press OK to exit the preferences and hover the mouse over any of the CPAP graphs.
4) Begin moving the mouse to the right, and note that when you reach an hour after the start of the session (not the day), the value shown in the top left of the graph strip begins to display the actual value, rather than 0.
5) Repeat the above steps but instead set the time back an hour, and start at the end of the sessions, rather than the beginning, moving the mouse to the left.
