AV-Trend represents the real-time trend display previously associated with DigiTrend, and is also included in AirVision's Site Node version. Because some restrictions in Digi-Trend have been removed, AV-Trend can also be used at a centralized system location in networks with continuous connections (IP polling), or even in slower networks to display trends of longer average intervals, such as hourly data.

Rather than use a button to 'toggle' between graphical and tabular display, AV-Trend displays the two modes side-by-side, with the option to hide one or the other.

Panel setups can be saved using the AirVision Favorites system, including the ability to automatically start the displays on application startup. Coupled with AirVision's auto-login function, the AirVision client could be put in the startup menu on a site PC and the displays always started on system restart.

Flags are represented by the Flag Editor colors on the 'dots'. The 'hover over' view from the Data Editor is also retained.

Data in the right-side grid can be selected, copied, and pasted.

Additional Ribbon functions allow the user to:

• Print or Export the Chart or the Grid (HTML, CSV, XLS, BMP, JPG, etc)
• Select a range of data in the grid and open that data in the Data Editor.

In the graph criteria, the user may select several customizations:

· Number of Hours in Lookback- This allows the user to dynamically define the width of the graph. After changing, the user should select “Manual Refresh” from
the ribbon to take effect. This preference is stored with any Favorite created.
· Use Dynamic Scaling- If selected, the data graph min/max is set based on the range of data, rather than the graph min/max configured in the Parameter settings editor.
· Suppress Flag Colors- If not selected, flagged data will be shown with “dots” with colors based on the Flag configuration. If selected, data will just be shown as the trend graph color. In both cases, hovering the cursor over the point will always show the flag, and the flag colors are still represented in the tabular/grid display.
