Figure C3.2.1 shows a horizontal trend display for an imaginary group (Furnace Temps 1) with two chan-
nels (Stack 1 and Stack2North)
Figure C3.2.1 Horizontal trend example
As shown in the fi gure, the group process values appear as though being traced on a chart which is roll-
ing from right to left (i.e the oldest sample is at the left edge of the chart, and the latest sample is at the
right edge of the chart). The point Descriptors, Span high and Span low values and process values (at the
time and date at the top left of the screen) appear in a table below the chart.
The amount of time across the width of the chart (the 'horizontal scale') can be edited from its default of
20 minutes by typing a new value in the box at bottom left of the page, and confi rming either by clicking
on the 'Set' button at bottom right or by using the pc's <Enter> key.
To return to the Trend Mode selection page, Click on the 'Trends' link at top left.
