Functions

plot

plot(...signals: list<int, float>)                     #1
plot(config: map<string><>, ...signals: map<string><>) #2

Plots given lists as individual signals (#1). Plots given signals using global config map and individual maps with series (#2).

Arguments

#1

signals - series to be plotted

#2

config - global config map, which includes following keys (all of them are optional):

KEY	TYPE	VALUE	DEFAULT
title	`string`	The title of plot written at the very top of it.	-
output	`string`	The output image file name. If passed, plot is not displayed.	-
format	`string`	The format of output image. Applicable only when `output` is passed.	png

Available formats:

png
jpg
bpm
gif
eps
pdf
svg
signals - a list of maps of following schema:

KEY	TYPE	VALUE	REQUIRED?	DEFAULT
name	`string`	The name of series (will be applied in legend).	Yes	-
y	`list<int, float>`	The data to be plotted.	Yes	-
x	`list<int, float>`	The X series (horizontal axis).	No	0, 1, 2, ...

Example

plot(fft(wave([@F#])));

plot({ title -> "Example plot", output -> "myFile", format -> "pdf" },
 { name -> "C", y -> wave([@C:32]) },
 { name -> "D", y -> wave([@D:32]) },
 { name -> "E", y -> wave([@E:32]) }
);

fft

fft(signal: list<int, float>)

Returns a signal passed through FFT/radix-2 algorithm as a list of floats.
