MinutesAtPressure Graph
The MinutesAtPressure (TimeAtPressure) Graph is the Pressure Graph transposed - with similar look and feel as other graphs.
The Y-Axis (pressure) becomes the X-Axis (MinutesAtPressure).
The X-Axis (Time) becomes the Y-Axis (duration in minutes).
The MinutesAtPressure Graph uses the configurable Plot and Overlay Settings from the Pressure Graph,
EPAP and IPAP(CPAP_Pressure) will both be conditionally displayed
Events (H, CA, OA, UA) are displayed as tick marks similar to the Pressure Graph.
Events (LL, CSR) are also displayed like the pressure Graph with lightgrap or lightgreen background coloring.
This gives the MinutesAtPressure a similar look and feel as other graphs.
The MetaData (top label Bar) now contains the total duration for each pressure pressure bucket (range of pressures) as well as the events that occured.
The MinutesAtPressure tool-tips now contains just the names of the Event Ticks (similar to the pressure Graph)
The tooltip information is minimal and only contains the name of the event and the number of occurrences for that pressure range.
On Mouse Over
1. Each data point will be highlight with a small dot.
2. Tooltips will be displayed for the appropriate Pressure Range and the respective data point will be displayed with a square box - similar to the current current implementation.
When there is no data available (the time selected is between sessions in a day) then "No Data" will be displayed.
When no graphs are selected then "Plots Disabled" will be displayed - just like the Pressure Graph.
The X-Axis start and end pressure now use the Machine limits. If plot data has a data outside the range is appopaitely updated.
Refactoring was done to
1. Reduce duplicate/similar instances of code
2. Shorten long methods
3. Enhance readability,
5. Add Dynamic Meta data for Pressure times and Events.
6. insure data accuracy.
7. Conditional compilation for features
Total Duration displayed by Minutes AT Pressure graphs is based on the actual waveform form files.
In some cases this duration is different that the session time indicated in the daily session information - due to reasons below.
Issues found while testing based on 1.2.0 base.
* Event Flags do not display short SPANS.
* Pressure Graph does not display short SPANS.
* sessions times (as displayed in daily session information) are not always the same as the first and last time in the waveforms.
for example for resmed the the session start time is about 40 seconds before the first sample in the waveform (eventlist).
also the session end time is not always the same as the last sample in the waveform. typically 1 second different (either before or after waveform).
* multiple eventlists in a session. time betwwen eventlists is small - under 1-2 minutes.
This is not the same as multiple sessions per day.
Naming convention
pixel == at point on the display area.
pixels == distance between to pixels
Pressure == a value in cmH20
Bucket == A range of pressures to collect the ammount of time in that pressure range
some messages from Apnea Board.
0000042: Graphs Daily "Time at Pressure" graph x-axis goes to -1 and plot trace showing behind other graphs
Graphs Daily "Time at Pressure" graph x-axis goes to -1 and plot trace showing behind other graphs On the "Daily" tab,
the Time at Pressure plot's x-axis minimum is a value of -1. i
Also, the plot traces on this graph jump to unreasonably high values (e.g., 508)
which are shown behind the other graphs above it.

0000038: Graphs any "Time at Pressure graph does not show the right pressure
Graphs any "Time at Pressure graph does not show the right pressure, i
e.g. CPAP with constant pressure at 7.5 cmH2O , but the Time at Pressure graph only has a peak around 6.2 cmH2O
" This is especially true when looking at data at constant pressure.
It was found with DV64 data, but is presumably true for other machine types as well as the graphs do not differentiate on machine types - to be confirmed All 2-high
