For Historical Trend Graphs, Data Block Display
Graphs, XY Historical Scatter Graphs and XY Block Display Scatter
Graphs, you can display up to 8 graphs on a single screen
(including called screens and popup windows) at the same time.

For Historical Trend Graphs, Data Block Display
Graphs, XY Historical Scatter Graphs and XY Block Display Scatter
Graphs, you can display up to 40 channels on a single screen
(including called screens and popup windows) at the same time. Any
subsequent channels do not display.
-
The maximum number of channels (number of lines)
that can be displayed on a single Data Block Display Graph is
20.
-
Coordinate points of the graph data are
calculated as a value between 1 and 1000. Even though values may be
outside the display range, if the converted values are within
range, they will display in the graph.
-
Do not draw other parts in the graph display
area. to draw pictures such as lines directly within the display
area, place the graph on base screen 9000 to 9999. If you draw
scale lines within the graph display area on base screens 1 to
8999, the scale lines will not show on the display unit. to display
a graph with scale lines on base screens 1 to 8999, load screen
9000 or higher.
On screen 9000 or higher, draw the graph and objects that overlay
the graph. Other parts such as switches may not operate
properly.
-
When using the graph area color with a graph with
no shape on base screen 9000 or higher, drawing is done in the
following order. As a result, if you draw on the graph display
area, or you set the base screen's background color, these draw
with a higher priority than the Graph Area Color.
-
Graph Area Color
-
Drawings such as Line or Rectangle, or Base
screen background color
-
Line Chart
-
You cannot use symbol variables set up as an
array in the graph display.
-
When dislaying multiple data block display graph
or XY block display scatter graph on one displayed screen, do not
duplicate each part's control address.
-
The display speed of graphs differs depending on
the location of the [Control Word Address]. Whether you use a
device/PLC address or use the read area (LS0020 or higher) of the
display unit internal devices. For more details, please refer to
the following.
19.10.3 Data Block
Display Graph Structure
-
When [Show Scale] is set to [Address] and a
communication error occurs, drawing is done using a value of
[0].
-
When the auxiliary line is set to [Address] and a
communication error occurs, drawing is done using a value of
[0].
-
When the display is updated, the graph display
area is filled in with a clear color and then the graph is
displayed again. Therefore the screen may flicker.
