Trend Style
You can select to display a trend as Standard or FIFO. When the user views a Standard Trend, the user must stop the sampling, and select the file to view. The FIFO Trend allows the user to view the last Trend file, and then to page through the files in chronological order. If the history contains 15 files, where File_1 is the oldest and the user is currently viewing the active file, paging back will display File_15. the user can then use the Slider to navigate back and forth in the file.
