can be references for the graph frame width is determined by the following
equation.
Graph frame width (number of dots) ≧ Number of memory table entries
S % Data Value (Line Attribute)
This attribute specifies the % data value at every polygonal line. For the speci-
fying method, the same is also true as the bar graph. Refer to page 142.
"% representation" cannot be performed for the polygon.
S Graph Line Type (Line Attribute)
This attribute specifies a graph line type among those as shown below. With
NT30C, line color can be selected out of eight colors. A graph width is fixed at
one
dot.
Solid line
Broken line
1-dot chain line
2-dot chain line
S Differences when A Broken Line Graph Is Displayed Using Percentage
Values
When % value is in the following range, the graph displaying method is re-
stricted as follows:
(1) In case of negative % value
A graph is displayed differently depending on the sign representation.
Without sign representation: Displayed in the same manner as 0%.
With sign representation:
tion.
(2) When an absolute value of % is from 100% to 999%
A graph is not displayed in this range of %. Only a part of % value within the
graph frame is displayed.
The values outside of this range are not displayed.
(3) When an absolute value of % is equal to or greater than 1000%
A value is not displayed in a graph in the same way as (2).
A graph is displayed in the negative direc-

Values outside the range are not displayed.
