Interpolation is a method of estimating and constructing new data points from a discrete set of known data points. This function generates uniform linear spaced interpolated curve by three methods: Linear, Cubic spline and Cubic Bspline.
To use this function:
In fact, the interpxy XFunction is called to complete the calculation.
Input 
Specifies the XY range to be interpolated. 

Method 
Specify the interpolation/extrapolation method.

Number of Points 
Specifies the number of interpolated points. 
X Minimum 
The minimum X value of interpolated curve. 
X Maximum 
The maximum X value of interpolated curve. 
Apparent Interpolation 
It is available only when the interpolation is performed on a graph. It specifies whether to use the apparent values for interpolation if the types of the axes scales have been changed to other types. 
Output 
Specifies the output XY data range
