Client Trend

AVEVA Historian Client Trend is a client application that lets you query tags from an AVEVA Historian database and plot them on a graphical display. Trend supports two different chart types: a regular trend curve and an XY scatter plot.

After you add tags to a trend chart, you can manipulate the display in a variety of ways, including panning, zooming, and scaling. You can customize any trend by configuring display options and set general options for use with all trends.

Before Trend can be used to query tag information from the database, the server must be running and you must have security access.

This section describes the basic procedures for working with regular trends. Most of this information also applies to XY scatter plots. For information specific to XY scatter plots, see Working with Scatter Plots.
