Tangent mode line
In the first bracketed field after LINE1 or LINE2, you select the line mode. Select
the TANGENT secondary softkey to set the tangent line mode. The pointer moves to
the second bracketed field as shown:
LINE1: [TANGENT ] LINE ON [Y1] between a point where
[ ]=[ ]
[ ][ ]=[ ]
In the second bracketed field, you specify which measurement curve you want to
analyze by selecting the related axis: Y1 or Y2 secondary softkey.
Enter a variable name and condition expression to specify the measurement point
for which you want to draw a tangent line.
LINE1: [TANGENT ] LINE ON [Y1] between a point where
[DGM ] = [MAX(DGM)*0.01 ]
[ ][ ]=[ ]
In addition, you can specify another condition if you position the pointer in the last
bracketed field shown above. Select the AFTER secondary softkey. AFTER is
displayed, and you can enter a second variable and condition expression. This sets
up a search start condition for finding specified point. (This setup is optional.)
For example, you can specify the following expressions to search for a measurement
point that satisfies the first condition after the second condition is satisfied.
LINE1: [TANGENT ] LINE ON [Y1] between a point where
[DGM ] = [MAX(DGM)*0.01 ]
[AFTER] [DGM ] = [MAX(DGM)
]
On GRAPH/LIST: GRAPHICS screen, LINE secondary softkey must be ON.
