@IY1
@IY1
Returns the value of Y1 coordinate at the cross point of LINE1 and LINE2.
Syntax: @IY1
This function calculates the cross point by using the following formula:
y
1
= y
1
+α
1
×(y
2
-y
1
)/(α
1
-α
2
)
Where,
y
1
: Value of Y1 coordinate at the cross point. If the Y1 axis is logarithmic scale,
this function returns 10
y1
.
y
n
: Y1-intercept of LINEn. If the Y1 axis is logarithmic scale, y
n
is the log
value of the Y1 intercept of LINEn.
α
n
: Slope of LINEn.
If LINE1 is parallel to LINE2, this function returns invalid data with the status
"Arithmetic error".
@IY2
Returns the value of Y2 coordinate at the cross point of LINE1 and LINE2.
Syntax: @IY2
This function calculates the cross point by using the following formula:
y
2
= y
1
+α
1
×(y
2
-y
1
)/(α
1
-α
2
)
Where,
y
2
: Value of Y2 coordinate at the cross point. If the Y2 axis is logarithmic scale,
this function returns 10
y2
.
y
n
: Y2-intercept of LINEn. If the Y2 axis is logarithmic scale, y
n
is the log
value of the Y2 intercept of LINEn.
α
n
: Slope of LINEn.
If LINE1 is parallel to LINE2, this function returns invalid data with the status
"Arithmetic error".
