Trending Historical Data

CygNet Software supports many ways to graphically display trend data. The following table provides basic information about each way and directs you to additional information. Unless otherwise noted, trend data for each item below originates in the VHS.

CygNet Feature	Description
CygNet Studio Trend Tool	The Trend Tool is an ActiveX control used in CygNet Studio and CygNet Vision screens to provide a customizable means to chart data in a number of useful formats, including line graphs, bar graphs, and area graphs.
CygNet Studio TheFrame/TheView Trend Property	The Default Trend is a property of TheFrame/TheView, but it has much in common with the Trend Tool.
CygNet Studio Tool-Specific Trends	Many CygNet Studio tools include a Trend option in Run mode. Some of these tools are the Button Tool, Text Tool, and Vector Image Tool. Trend options include the Single-Point Trend and Single-Point Trend with Rollups. Although the Group Grid Tool does not have a Trend option, items included within its grid do. Although the WatchList Tool does not have a Trend option, items included within its grid do.
