The Mark Data Points option enables you to display a black dot at each place that a plotted point occurs along a series.

This option enables a trend to progress forward in time even if the latest poll has not yet occurred. When the next poll occurs, the series line updates to reflect the slope change, if any.

The intervals at which the trend moves forward are defined in Run mode using the Auto Extend Rate settings. In Edit mode, they are defined on the Data page.

When in use, Enable Auto Extend causes most Properties options to be dimmed. Disable auto extend to access Properties.

You can use Enable Auto Extend in conjunction with Extend Last Value. Doing so allows the trend to move forward in time while displaying a series from its latest plotted point up to the latest time displayed on the trend.

This option is used in conjunction with Enable Auto Extend. The intervals at which the trend moves forward are defined in Run mode using the Auto Extend Rate settings. In Edit mode, they are defined on the Data page.

Use the Forward and Backward options to scroll according to the predefined intervals. You can also use to scroll forward and backward through trend time.

In Run mode, scroll sizes are defined by doing the following:

• Using the Toolbar > Configuration option
• Using the Properties > Data Window option

In Edit mode, scroll sizes are defined by doing the following:

• Using the Data options
• Using the Toolbar options

For an embedded Trend Tool, check Maximize or press M to enlarge a trend to fill your computer screen. Uncheck Maximize, press M, or press F11 to return the trend to its original size.

For a default trend, check Maximize, press M, double-click the trend's title bar, or press F11 to enlarge the trend to fill your computer screen. Uncheck Maximize, press M, double-click the trend's title bar, or press F11 to return the trend to its original size.

The Undo Zoom option returns a screen to its unzoomed state; it is only enabled after you have zoomed.

To zoom, left-click on a trend and continue holding down the mouse button while you draw a zoom area. Release the mouse button when you have drawn the desired zoom area. You can zoom multiple times over the same area.

To unzoom, right-click on the trend and click Undo Zoom; you cannot incrementally zoom out. Refreshing the trend automatically returns it to 100%, if zoomed. Enabling auto-extend also automatically returns the trend to 100%, if zoomed.

You can use the mouse scroll button to scroll forward and backward in time when zoomed. You can also middle-click and drag.

If applicable, add an annotation to a Trend Tool. See also Notes.

Click Print to print the displayed trend.

The Export option enables you to export a trend in one of several file formats, most of which are graphics files. Depending on the file type selected, additional options might appear on the Exporting X dialog box.

The Text/Data option leads to an additional dialog box that enables the configuration of the exported text/data file. This includes being able to select specific data points on a point-by-point basis.

The Export option is unavailable if you are in Auto Extend mode.

See Exporting Trends for more information.

Select Quick Export to export the labels and data of each series directly to a temporary comma-separated value file (CSV). Save to a location of your choice.

See Exporting Trends for more information.

Updates the trend screen. Refreshing the trend automatically returns it to 100%, if zoomed.

Two Restart options are available as follows:

• Clear Cached Values clears caches and forces the trend to read values from the VHS. It is best to clear the cache if you significantly change the time range or if you change the type of data you are graphing (for instance, from rollup data to raw data).
• Don't Clear Cached Values redraws the screen using cached values, if available. The trend caches values as they are retrieved from the VHS. When you scroll back in time in the view window, values previously retrieved from the VHS might not be visible; however, they are still available in the cache. When you scroll back to the right, values are retrieved from the cache and not the VHS.

Stops an in-progress data retrieval.
