With Alertify's dashboard, users can view live and historical data for each graph on their dashboard. Viewing historical data of your property is helpful if you wish to take a look at past guest violations. Here is how to view the historical data on your Alertify dashboard:

1. Navigate to your "units" tab and click on the unit's name that you would like to view data for.

2. Scroll down to the graph you would like to view historical data for and click on the calendar button in the top right-hand corner above the graph. Each graph has its own calendar.

3. Choose two dates on the calendar to view the historical data for that time range, and then the graph will reflect the noise or smoking levels for the selected time range. To save an image of the graph, simply click on the save button next to the calendar button and a png will download.
