Configure Trends

Before you can view trends, the following configuration tasks need to be completed:

• Add a Trend Tag

• Create Pages for Trend Graphs

• Define Trend Interpolation.

  Note: If a variable tag is associated with a driver that supports the Driver Runtime Interface (see Retrieving Time-stamped Data from I/O Devices), you can define a trend tag as a pure-event trend. See Configure Event Trends for a DRI Driver.
