Colormap

Maps an array, or one dataset component, through a colormap to RGBA colors for a Plot's colors input. It supports reversal, color limits, log scaling and alpha.

Inputs

Port	Accepts	Required	Description
`x`	primitive(array) dataset	required	Scalar values to map (array, or a dataset component)

Parameter ports

Added from the Parameters pane (⊕). While connected, each drives its parameter.

Port	Accepts	Mode	Description
`alpha` Alpha	primitive(array) primitive(number)	opt-in	Per-row alpha override (a scalar, or one value per row)
`clim`	primitive(array)	opt-in drives `clim`	Drives the Color limits parameter while connected

Outputs

primitive(array)

Parameters

Parameter	Kind	Default	Choices / range	Notes
Component `component`	choice	none	values \| values_r \| values_theta \| values_phi \| scale_r \| scale_theta \| scale_phi \| points \| points_r \| points_t \| points_p
Colormap `cmap`	colormap	`viridis`
Reverse colormap `reverse`	bool	`false`
Color limits `clim`	range	none		⇄ port
Log Scale `log_scale`	bool	`false`
Alpha `alpha`	float	`1`	0 to 1, step 0.05
