ⓔ

Reuse Button

Move the result data[ⓕ] to Input text field[ⓒ] for getting more accurate curve by use increased result data

ⓕ

Result Output field

Indicates the point(x,y) of array which compose a fitting curve

ⓖ

Coordinates [Y]

The Y value which the point device indicate in drawing canvas[ⓐ]

ⓗ

Coordinates [X]

The X value which the point device indicate in drawing canvas[ⓐ]

ⓘ

Status field

The region which display the status of processing, error, exception, etc

ⓚ

Option for quadratic spline

Applicable options([First] and [Last]) for only Quadratic spline Interpolation. You can get more accurate fitting curve of Quadratic spline as you compare two results of alternative.

ⓛ

Degree of Polynomial

Indicates degree[Order] of polynomial regression method

ⓜ

Degree of Fourier series

Indicates degree[Order] of fourier sereis regression method.

ⓝ

Result funtion field

The region which display result expression in terms of explicit type of function[Y=F(X)]. It display result only when one of the least squares regression methods is applied as a fitting method.

ⓞ
