Pen Record Type
With the pen recorder type, the latest drawing position is always displayed at the
edge of the graph area. Therefore, depending on the number of data in the latest
page, old data may be displayed discontinuously as shown below (Internally, the
data is recorded continuously.)
Latest data
For trend graphs, the graph area is displayed in accordance with the General
settings, and the broken line is displayed in accordance with the Settings (prop-
erties 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 162).
• When multiple broken lines are registered, they overwrite each other in the or-
der they were registered. When broken lines overlay each other they are dis-
played according to the XOR principle (page 41), and consequently the line
style and color may differ from those specified. The same principle applies
when a broken line overlays the graph frame.
Trend graphs have no input function.
Trend graphs have no output function.
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 162).
• For details on how numeric values are stored in numeral memory tables, refer
to 2-3-1 Numeral Memory Tables (page 64).
• 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.
