7.3 Configuring Historical Trends

Historical Trending permits the assignment of any non-text (i.e., non-ASCII) point in the Historical database
or Historical Block database to a multi-point trend display, whether or not the point is included in a hierar-
chical display. A maximum of 8 points can be trended on a multi-point display. All points on a multi-point
trend display need not have the same data collection rate.

Once a trend has been chosen, the trend display for that index number appears in the Operator Window. If
no parameters have yet been configured for the trend, a template of the historical trend display appears.
This contains all the basic parts of an historical trend display, but has no legend, no trace assignments, and
default scale bar limits of 0.00 and 100.00. Scale bar limits have a default precision of two decimal places
to the right of the decimal point.
