Add a Data Set to a Trend
Just as you would add tags in defining a trend, you can add columns
chosen from a data set. Each column is plotted as a separate trace,
however, the data set columns that appear on your trend do not appear in
the Point Properties dialog box.
If the query returns a null value, the trace displays the discontinuity.
Information from more than one data set, or more than one column from
the same data set may be plotted on the same trend. The trend assumes the
first time column found in the data set provides the time stamps for the
column(s) selected for trending.
You can manipulate trends containing data from data sets just as you
would other trends, by using functions such as:
 Trend Zoom
 Scrolling
 Trend Cursor
 Time Range
 Revert Time Ranges
 Autorange
 Markers
To add a data set to a trend:
1. In Build mode, open a display.
2. On the Drawing toolbar, click .
3. Click in the display where you want to add the trend and drag the
pointer to form a rectangle into which the trend will be placed.
When you release the mouse button, the Define Trend (page 110)
dialog box appears.
