Direction of broken line graphs
The directions of broken line graphs depending on the setting made for “Direc-
tion” are shown below. The “direction” of a broken line graph means the direction
in which the values in numeral memory tables are plotted, starting from the nu-
meral memory table with the smallest table number and proceeding through pro-
gressively larger table numbers.
The 100% value is at the top of the frame when the “Direction” is a lateral one and
the right of the frame when the “Direction” is a longitudinal one.

Number of vertices
The maximum number of vertices (numeral memory tables) that can be dis-
played in one broken line is 320, but since a minimum interval of 1 dot is actually
required between memory tables, the following restriction applies depending on
the width (number of dots) of the graph frame.
Width of graph frame (number of dots) “No. of Points”
S
Interval between numeral memory tables
The display interval between memory tables can be set individually for each
memory table. Adjust the intervals as required.
When “Even” is set for the “Interval Type”, the intervals are arranged evenly so
as to make use of the entire width of graph area.
