Drawing Width
The drawing width is the interval at which successive data are drawn in the direc-
tion of motion. If a value outside the display area of the graph is specified, the
graph will not be displayed.
Line Drawing Method
The graph is drawn as shown below depending on the settings made for Type
and Direction.
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.
When Standard Is Set for Type
With the standard type, the latest drawing position moves in the direction of mo-
tion specified by Direction with the passage of time. If the direction of motion is
right, the display changes as indicated below. When the line reaches the edge of
the graph area, the line is cleared and then displayed again from the beginning.
