11	Short Name and Equipment Name	When a point is added from an equipment and space context, the graph shows the short name, point label, equipment name, and equipment serving space information of the point. When a point is added from a building network context, the graph shows the name and Fully Qualified Reference (FQR) of the point.
12	Trend Legend	Shows what point each trend series correlates to. The legend includes the short name of the point, the equipment the point resides on, the line marker and color, and a triangle icon (if the point or equipment is disabled). Tap or click on specific trend legend to highlight the trend series on the trend graph. Doing so also changes the y-axis to reflect that trend series' unit of measure. You can move points between the two graphs by dragging the Drag icon in the legend:

14	Y-axis	Shows the unit of measure and scale of the selected trend series. The y-axis changes depending on the trend series that is selected. On initial load, the y-axis displays the unit of measure and scale of the first trend series available. When viewing analog (numeric) points, binary points, and multi-state points in the same trend graph, the y-axis splits to show the analog point unit of measure on the top portion of the graph and the binary or multi-state point unit of measure on the bottom portion of the graph.

For analog (numeric) points, live raw data displays when you view seven days or less of trend data.

For analog (numeric) points, averaged data displays when you view greater than seven days of trend data:

When you view greater than seven days to less than two months of trend data, a daily average of data is plotted. You can drill down to a day and to an hour.
When you view two months to one year of trend data, a monthly average of data is plotted. You can drill down to a month, then to a day, and then also to an hour.
When you select a Custom Range greater than one year, or when you select All Time for a customer site that has more than one year of trend data, a yearly average of data is plotted. You can drill down to get an average of months, days, hours, and also raw data. Similarly, you can roll up to the yearly average again.

Note: The raw data limit for analog points is 50,000 samples per point. This means that when you view seven days or less of trend data, only up to 50,000 samples per point are plotted in the trend graph.

For binary points and multi-value points, raw data displays regardless of the date range you select.

Note: The raw data limit for binary points is 50,000 samples per point. This means that when you view trend data for any date range, only up to 50,000 samples per point are plotted in the trend graph.
