<br><br>
The Overview page shows the charts as a histogram (bar graph) where every bar represents one day of data. Select which chart you want included by using the '''Chart selector'' pop-up menu.

'''Select which dates you want''' to include by clicking on the '''Date range selector'''. The date ranges span from one week to one year. In addition, you can select "Everything" or else specify a range by selecting "Custom". Note that if you have several years of data it can take a few minutes for the chart to be calculated - in this time Oscar doesn't appear to be doing anything, but just be patient and it will eventually show the chart.

==Chart interpretation==
===AHI chart===
This chart shows the AHI each day, with different colours depicting different types of events (ie hypopnea, obstructive apnea, central apnea, unclassified apnea).
If you place your mouse cursor over the bar for a given day, a small "balloon" will pop up giving the date and the numerical breakdown of the event types.

===Usage chart===The Overview page Usage chart shows the charts how many hours per day your machine was used. The bars are colour-coded as a histogram (bar graph) where every bar represents one day follows:'''Red:''' Hours less than required for compliance. This is normally 4 hours per night but can be adjusted in File | Preferences | CPAP.'''Blue:''' Hours in excess of compliance, with full data. Select which chart you want included by using the '''Grey:'Chart selector'' popHours more than compliance, but only summary data. This might be seen if you left the SD card out of the machine. On older machines such as the Resmed S9 series, a grey day can occur if the card hasn't been downloaded for over a week and the detailed data is over-up menuwritten.
