Built-in Functions
@IX
@IX
Returns the value of X coordinate at the cross point of LINE1 and LINE2.
Syntax: @IX
This function calculates the cross point by using the following formula:
x =(y
2
-y
1
)/(α
2
-α
1
)
Where,
x : Value of X coordinate at the cross point. If the X axis is logarithmic scale,
this function returns 10
x
.
y
n
: Y-intercept value of LINEn. If the Y axis is logarithmic scale, y
n
is the log
value of the y intercept of LINEn.
α
n
: Slope of LINEn.
If LINE1 is parallel to LINE2, this function returns invalid data with the status
"Arithmetic error".
@IY
Returns the value of Y coordinate at the cross point of LINE1 and LINE2.
Syntax: @IY
If there are Y1 and Y2 axes, this function returns the value for selected axis.
This function calculates the cross point by using the following formula:
y = y
1
+α
1
×(y
2
-y
1
)/(α
1
-α
2
)
Where,
y : Value of Y coordinate at the cross point. If the Y axis is logarithmic scale,
this function returns 10
y
.
y
n
: Y-intercept value of LINEn. If the Y axis is logarithmic scale, y
n
is the log
value of the y intercept of LINEn.
α
n
: Slope of LINEn.
If LINE1 is parallel to LINE2, this function returns invalid data with the status
"Arithmetic error".
