visbrain.utils.array2colormap¶

visbrain.utils.array2colormap(x, cmap='inferno', clim=None, alpha=1.0, vmin=None, vmax=None, under='dimgray', over='darkred', translucent=None, faces_render=False)[source][source]¶

Transform an array of data into colormap (array of RGBA).

Parameters:

x: array Array of data cmap : string | inferno Matplotlib colormap clim : tuple/list | None Limit of the colormap. The clim parameter must be a tuple / list of two float number each one describing respectively the (min, max) of the colormap. Every values under clim[0] or over clim[1] will peaked. alpha : float | 1.0 The opacity to use. The alpha parameter must be between 0 and 1. vmin : float | None Threshold from which every color will have the color defined using the under parameter bellow. under : tuple/string | ‘dimgray’ Matplotlib color for values under vmin. vmax : float | None Threshold from which every color will have the color defined using the over parameter bellow. over : tuple/string | ‘darkred’ Matplotlib color for values over vmax. translucent : tuple | None Set a specific range translucent. With f_1 and f_2 two floats, if translucent is : (f_1, f_2) : values between f_1 and f_2 are set to translucent (None, f_2) x <= f_2 are set to translucent (f_1, None) f_1 <= x are set to translucent faces_render : boll | False Precise if the render should be applied to faces

Returns:

color : array_like Array of RGBA colors
