With/without a graph frame
Select whether or not the graph frame (boundary line of a graph display area)
which indicates the effective display range is displayed.
←
This frame is not displayed if
“Graph frame: No” has been

•
% Data value
Data value corresponding to 0%, 100%, –100% can be specified. % Data val-
ue can be specified by two methods: by directly specifying a numeric value
and/or by referring to the Numeral Memory Table.
- Directly specifying method
Numeric value from 0 to 99999999 (max. 8-digit) is specified. It is necessary
to set that 0% value is more than –100% one, and 100% value be more than
0% one without fail.
- Memory table referring method
Numeral Memory Table number to be referred is specified instead of a nu-
meric value. With this method specified, each data value can be changed
from the Host during operation.
•
% Display
% Value can be displayed.
% Value can be calculated according to the following equation:
% Value =
Referred Numeral Memory Table value – 0% Value
100% Value – 0% Value (or 0% Value – (–100% Value))
100
Attribute of numeric value displayed is the same as that for character display.
Refer to the “Numerals which can be Displayed” (page 135).
•
Sign display and display method
Select whether or not the bar graph which indicates a value below 0% is dis-
played.
