@L2G2
Returns the slope of LINE2 for Y2 axis.
Syntax:
@L2G2
This function calculates the slope by using the following formula:
• If X and Y2 axes are both linear scaling:
a
= (y
1
-
y
0
)/(x
1
-
x
0
)
• If X axis is logarithmic scaling, and Y2 axis is linear scaling:
a
= (y
1
-
y
0
)/(log x
1
-
log x
0
)
• If X axis is linear scaling, and Y2 axis is logarithmic scaling:
a
= (log y
1
-
log y
0
)/(x
1
-
x

)
• If X and Y2 axes are both logarithmic scaling:
a
= (log y

-
log y

-
log x
0
)
