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 begin-
ning.
