@L1G1
@L1G1
Returns the slope of LINE1 for Y1 axis.
Syntax: @L1G1
This function calculates the slope by using the following formula:
• If X and Y1 axes are both linear scaling:
α = (y
1
− y
0
)/(x
1
− x
0
)
• If X axis is logarithmic scaling, and Y1 axis is linear scaling:
α = (y
1
− y
0
)/(log x
1
− log x
0
)
• If X axis is linear scaling, and Y1 axis is logarithmic scaling:
α = (log y
1
− log y
0
)/(x
1
− x
0
)
• If X and Y1 axes are both logarithmic scaling:
α = (log y
1
− log y
0
)/(log x
1
− log x
0
)
