[Display Functions]
For trend graphs, the graph area is displayed in accordance with the “General” set-
tings, and the broken line is displayed in accordance with the “Settings” (properties
of each line) settings.
For details on the method of display depending on the “General” and “Settings”
(properties of each line) settings, refer to “Common Attributes” (page 392).
S When multiple broken lines are registered, they overwrite each other in the order
they were registered. When broken lines overlay each other they are displayed
according to the XOR principle (page 260), and consequently the line style and
color may differ from those specified. The same principle applies when a broken
line overlays the graph frame.
[Input Functions]
Trend graphs have no input function.
[Output Functions]
Trend graphs have no output function.
[Processing Functions]
Trend graphs calculate the percentage value in accordance with the settings made
for “Settings” (properties of each line).
For details on the calculation method depending on the “Settings” (properties of
each line) settings, refer to “Common Attributes” (page 392).
[Relationship with Other Elements]
S For details on how numeric values are stored in numeral memory tables, refer to
7-3-1 “Numeral Memory Tables” (page 284).
S Trend graphs overlap with other elements in accordance with the order in which
they were registered for the screen with the Support Tool. However, the way in
which they overlap can be changed with the Support Tool.
Reference: Do not overlap percentage displays and other elements within the area in which a
trend graph is plotted. This can cause the graph to be displayed incorrectly.
