It is possible to display more than one broken line graph in the same frame so
that they can be compared.
100%
0%
–100%
With broken line graphs, a 100% value, 0% value and –100% value can be set
for each broken line in order to calculate and display the numeral memory table
values in percentage terms. However, there are no percentage displays for indi-
vidual numeral memory tables.
• One broken line graph frame can be registered for one screen. (Same for win-
dow screen.) For an overlapping screen comprising 8 child screens, up to 8
broken line graph frames can be displayed on one screen. Total maximum of
256 broken lines can be registered for one screen regardless of the number of
frames. (Same for window screen.)
There is no restriction on the number of broken line graph frames that can be
registered for one screen data file: any number can be registered as long as
the data file capacity is not exceeded. However, if a large number of ele-
ments are registered, check that the restrictions on element display are
complied with by referring to Display Restrictions (page 425).
• The contents of up to 320 consecutive numeral memory tables can be dis-
played in one broken line.
The relationship between the properties of a broken line graph and the display
results is indicated below.
In this example, the values in 11 numeral memory
tables are displayed with the sign indicated.
