Comparing readings to previous month or year

If data exists for the same period in the preview month or year, you can include the historical data on the same graph as the queue item data.

1. Click the queue item to select it.

2. In the top pane, click Diagnostics.

3. In the Readings pane, select the historical period checkbox in the legend to the right of the graph.

   • Last Month. Displays the same time period of the previous month. For example, if the queue item time period starts on 5/17/2012 and ends on 5/20/2012, check this box to display the data from 4/17/2012 to 4/20/2012.

   • Last Year. Displays the same time period of the previous year. For example, if the queue item time period starts on 5/17/2012 and ends on 5/20/2012, check this box to display the data from 5/17/2011 to 5/20/2011.

     Note: If no data exists for the previous month or year, the checkbox does not appear in the legend.
