Please refer to the following for models that
support XY Historical Scatter Graphs.
1.5 Supported
Features
-
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 that can be
displayed on a single XY Historical Scatter Graph is 10.
-
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

Graph
-
Graph will not be displayed when there is invalid
data in either X-axis or Y-axis.
-
Since the calculation method of the coordinates
of [Scale] and [Auxilary Line] are different, the coordinate
position may be different even if the values are same.
-
The number of data (coordinates) in a normalized
display is up to 512.
-
The order of drawing each graph is as follows.
However, after changing normalized values and only draw (bit 0
turns ON) is run, normalized data is drawn on top of the XY
Historical Scatter Graph.

XY scale
-
X- and Y-axis auxiliary lines

-
XY Historical Scatter Graph
-
The number of data (coordinates) you can display
in one channel is the [Occurrences], set from the [Common Settings]
menu's [Sampling] settings.
-
From the [Common Settings] menu's [Sampling]
settings, in the [Mode] tab when you define a [Data Clear Bit
Address], the graph is cleared when the specified bit address turns
on. In the [Mode] tab's [Extended Settings], when the [Overwrite
old data after finishing the specified cycles] check box is
selected, the graph is cleared when the [Data Full Bit Address]
turns on.
-
When you change screens, some of the previous
sampling data may appear again.
-
When the sampling [Occurrences] is large, the
first time to draw the graph may take awhile. The following is an
example of the time it takes to draw the first time.

-
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 Condition] is set to [Display
When Bit ON] and a communication error occurs, the graph will not
display. When using [Display When Bit OFF] and a communication
error occurs, the graph will continue to display.
-
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.
