Topic 8.1.1: InTouch Trends
InTouch Time Trends
- You can create trends that graphically show data collected from an InTouch application. WindowMaker includes a set of utilities and wizards that enable you to create historical and real-time trends. The following figure shows an example of an InTouch Average/Scatter trend.
- A historical trend shows log data collected from the past and stored in InTouch data repositories.
- Using a distributed history system, you can retrieve historical data from any InTouch historical log file located on an accessible network node. The distributed history system extends the retrieval capabilities of historical trends to include remote log databases.
- Real-time trends update continuously to show data as it occurs over relatively short periods. You can use WindowMaker’s Real-time Trend tool to create a trend object in a window. If the optional 16-Pen Trend tool is installed, you can also create real-time trends that show data from up to 16 tags.
- Real Time Trend from the Drawing toolbar to show the real-time values of up to four tags in a graph.
- 16-Pen Trend from the Wizards panel to show historical or real-time values of up to 16 tags in a graph.
- Simple Historical Trend from the Drawing toolbar to show the historical values of up to eight tags in a graph.
- Advanced Historical Trend from the Wizards panel to show the historical values of up to eight tags in a graph.
