scatterfit(x, y, [degree])

Input: x, y, degree · Output: no output

What it is

Draws a scatter of equal-length numeric Vecs x, y plus a polyfit trend line. degree (integer, positional, default 1) is the polynomial degree, sampled densely over x's range.

Overloads

One call shape — this function is not overloaded.

Code	Input	Output	Description
`scatterfit(x, y, [degree])`	`x` VecDraws a scatter of equal-length numeric Vecs `x`, `y` plus a `polyfit` trend line. `y` VecDraws a scatter of equal-length numeric Vecs `x`, `y` plus a `polyfit` trend line. `degree` optional`degree` (integer, positional, default 1) is the polynomial degree, sampled densely over `x`'s range.	no output	—

Examples

From the documentation, and run by the build -- the output and the figure below are what the engine actually produced. Simplest first.

scatterfit(t, y, 2)   # degree-2 polynomial fit through the scatter

How it works

scatterfit(x, y, [degree]) -- scatter points plus a polyfit trend line (default degree 1) sampled over x's range.

From the note above this builtin in the interpreter, where the reasoning was written down as it was built.
