4-5-3 Broken Line Graph Setting
A broken line graph displays multiple present value of Numeral Memory Table by
a single polygonal line. This allows variation of continuous values of the Numeral
Memory Table to be seen at a time.
Example displaying 11 Numeral
Memory Table values with signs
100%
–100%
10
0%
For a broken line graph, a single graph frame can be shown in a screen and a
maximum of 256 graphs can be registered in the graph frame. A single broken
line can display a maximum of 512 Numeral Memory Tables. However, the maxi-
mum number of numeral memory tables that can be displayed on one screen is
also 512.
•
Reference table
Specifies the first memory table number of the series of referenced memory
tables.
Although it is possible to select either “direct” or “indirect” as the reference
method with the support tool, only the “direct” setting is meaningful when using
an NT620S/NT620C.
It is not possible to use hexadecimal values for broken line graphs. If hexadeci-
mal values are specified in numeral memory tables referenced to obtain graph
values, the graph will not be displayed. The letter “F” may be used to indicate
negative values, but make sure that no hexadecimal values are written.
Broken Line Graph Attributes
When using an NT620S/NT620C, the following attributes can be used when dis-
playing broken line graphs.
•
Graph frame
This attribute specifies a rectangular area used to display a graph. This area
can occupy the following range:
NT620S:
Max. 640 dots horizontally x 400 dots vertically
NT620C:
Max. 640 dots horizontally x 480 dots vertically
The following setting can be performed for a graph frame.
- Frame display
With the “Frame Display” specified, 1-dot width frame line is displayed out-
side of the frame area. Color of a frame line can be selected out of eight col-
ors.
- Background color in a frame (NT620C only): 8 colors
Separate background color can be specified for positive and negative value
display area.
