 heatmap(options: object, source: Stream): Stream

Simple Heatmap UI component. The heatmap works like a sonogram
visualization (sliding window).

Parameter	Type	Default	Description
options	object		Heatmap options
options.duration	number	5	Duration of the window
options.refresh	number	50	Refresh rate (ms)
options.legend	string	''	Plot legend
source	Stream		Input stream (scalar or vector)

Returns Stream Scalogram stream

Example

noise = periodic(20).rand({ size: 20 }).heatmap();

 looper(options: object, source: Stream): Stream

Data Looper UI component. This module allows to record a buffer of Stream
data that can be looped.

Parameter	Type	Default	Description
options	object		Looper UI options
options.refresh	number	50	Refresh rate (ms)
options.stacked	boolean	false	Specifies if curves should be stacked (by default, curves are superposed)
options.fill	string	'none'	Plain fill options: - 'none': no plain filling (defaut) - 'bottom': fill from bottom - 'middle': fill from middle - 'top': fill to top
source	Stream		Input Stream (scalar or vector)

Returns Stream Output Stream: either unchanged input stream (in
'thru' or 'recording' modes), or loop of the recorded buffer (in playing
mode)

Example

data = periodic(10).rand().mvavrg({ size: 30 }).plot();
l = data.looper().plot();

 nodes(options: object, source: Stream): Stream

Nodes UI component with nodes interface. Multibuffer. Records to a global buffer.

Parameter	Type	Default	Description
options	object		Nodes options
options.name	string	''	Buffer name
options.refresh	number	50	Refresh rate (ms)
options.stacked	boolean	false	Specifies if curves should be stacked (by default, curves are superposed)
options.fill	string	'none'	Plain fill options: - 'none': no plain filling (defaut) - 'bottom': fill from bottom - 'middle': fill from middle - 'top': fill to top
source	Stream		Input Stream (scalar or vector)

Returns Stream Unchanged Input Stream

 plot(options: object, source: Stream): Stream

Simple Plotter UI component.

Parameter	Type	Default	Description
options	object		Plot options
options.duration	number	5	Duration of the window
options.refresh	number	50	Refresh rate (ms)
options.legend	string	''	Plot legend
options.stacked	boolean	false	Specifies if curves should be stacked (by default, curves are superposed)
options.fill	string	'none'	Plain fill options: - 'none': no plain filling (defaut) - 'bottom': fill from bottom - 'middle': fill from middle - 'top': fill to top
source	Stream		Input Stream (scalar or vector)

Returns Stream Unchanged Input Stream

Example

p = periodic(20).rand({ size: 3 })
  .plot({ legend: 'Simple plot', stacked: true });
runEffects(p, newDefaultScheduler());

 recorder(options: object, source: Stream): Stream

Recorder UI component. Multibuffer. Records to a global buffer.

Parameter	Type	Default	Description
options	object		Recorder options
