On the Summary tab for each property you will find a "Metrics Summary" table. You can customize this table to look at the metrics and time periods that are most important to you by clicking on "Change Metrics" or "Change Time Periods" above the chart.
The time periods will default to the Energy Baseline and Current dates.
This is a quick and easy way to look into issues because if you see an unexpected "Not Available," you can click on it to get the reason why.
