Change Request - OSCAR overview Line chart

Change Request - OSCAR overview Line chart
Hi Team,
In overview Tab, bar graphs are hard to track the trend, so is there a way to have an option to change the graph to line chart instead?

Also can you please add option to export all details, e.g. Tidal volume, respiratory rate, minute volume,...etc, so we can study more details about the trend via excel processing for such important informations.

Thanks,

I'll log your suggestion for a line chart option to a bar chart in the Overview tab.

Are you saying you want more details added to File/Export CSV?
The current version of OSCAR is 1.2.0.  We recommend upgrading from any earlier version.

Thanks...yes, since thise details can be seen only on overview tab and can't be exported , again for example Tidal Volume.

Right now, what gets exported are session or daily statistical values.
Adding periodic values will create considerably bigger files, since the csv format is not particularly efficient at that.
I'm not familiar with the PR data formats, but the edf format that Resmed uses is actually a good format for this kind of repetitive data.
Creating minute by minute averages from OSCAR's database will be, I think, a non-trivial project.

I see...to overcome this, you might limit the CSV format for such details to be only on daily basis (not min. By min.).... practically, this mean you just export the overview graphs tab information which are already in daily basis (not min
 By min.).

Hope I was clear in my suggestion.

Can you please eloborate more on ResMed edf format?, Is this the raw data I got from the MacroSD from the unit, or data processed via their website/application?

If its the later one, so unfortunately non-US residents can use their portal as its transffered via US GSM carriers only from the unit directly.

I think it would be possible to add the various values on a session or daily basis. Right now it exports the median (or average), the (90 or 95) percentile and the max for various parameters, and adding TV, MV and RR and some others should be fairly easy.


The edf format I mentioned is a mostly text format described at https://www.edfplus.info 

There is a very nice browser at https://www.teuniz.net/edfbrowser/ 

It is the format of the files in the DATALOG directory on Resmed SD card, and is what OSCAR uses when it imports data.

pholynyk, it's been more than 2 years since I looked into it but at the time I was unable to figure out how to access the underlying event by event level flow limitation data for export to a spreadsheet. brain fog was pretty bad back then so maybe I just missed it.

I did not and do not trust the flow limitation stats in SH and oscar and wanted to play around with those numbers to check for accuracy. great if you can add flow limitation to your list of "some others" to add if you haven't already.
