Graphs
Trend graphs represent the changes over time in the contents of a numeral
memory table as one line.
It is possible to display more than one such line in the same frame so that they
can be compared.
There are two types of trend graph: the standard type, where the graph is drawn
as though a pen were moving across paper, and the pen recording type, where
the graph is drawn as though the paper were moving under a pen.
With trend graphs, a 100% value, 0% value and –100% value can be set for each
line in order to calculate and display the numeral memory table values in per-
centage terms. The current percentage can be displayed.
Past values can be recorded, and then displayed by back tracking (the logging
function), and the contents of numeral memory tables can be collected even
while other screens are displayed (the background function).
• One trend graph frame can be registered for one screen. (Same for window
• If the set sampling cycle is shorter than the time taken for display update pro-
screen.) For an overlapping screen comprising 8 child screens, up to 8 trend
graph frames can be registered on each screen. Total maximum of 50 broken
lines can be registered on each screen. Total maximum of 50 broken lines can
be registered for one screen regardless of the number of frames. (Same for
window screen.)
cessing, sampling results that cannot be processed in time are skipped and the
data will not be displayed correctly.
There is no restriction on the number of trend graph frames that can be reg-
istered 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 425).
In the case of trend graphs comprising past values recorded with the logging
function, up to eight broken lines can be registered for one screen.
