7-10-3 Broken Line Graphs
[Function Outline]
Broken line graphs represent the contents of multiple consecutive numeral
memory tables as one broken line. They enable the values of consecutive numer-
al memory tables to be taken in at a glance.
It is possible to display more than one broken line graph in the same frame so that
they can be compared.
In this example, the values in 11 numeral memory
tables are displayed with the sign indicated.
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 individual nu-
meral memory tables.
[Restrictions]
S
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 bro-
ken 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 elements are
registered, check that the restrictions on element display are complied with by
referring to “Display Restrictions” (page 644).
S
The contents of up to 320 consecutive numeral memory tables can be displayed
in one broken line.
S
Broken line graphs cannot be specified indirectly using a numeral memory table.
They must be specified by direct reference.
