plotly.js/src/traces/carpet/axis_attributes.js

Lines 466 to 486 in 206d117

	_deprecated: {
	title: {
	valType: 'string',
	editType: 'calc',
	description: [
	'Deprecated in favor of `title.text`.',
	'Note that value of `title` is no longer a simple',
	'*string* but a set of sub-attributes.'
	].join(' ')
	},
	titlefont: fontAttrs({
	editType: 'calc',
	description: 'Deprecated in favor of `title.font`.'
	}),
	titleoffset: {
	valType: 'number',
	dflt: 10,
	editType: 'calc',
	description: 'Deprecated in favor of `title.offset`.'
	}
	},

Instead one should use another title attribues:

plotly.js/src/traces/carpet/axis_attributes.js

Lines 30 to 63 in 206d117

	title: {
	text: {
	valType: 'string',
	dflt: '',
	editType: 'calc',
	description: [
	'Sets the title of this axis.',
	'Note that before the existence of `title.text`, the title\'s',
	'contents used to be defined as the `title` attribute itself.',
	'This behavior has been deprecated.'
	].join(' ')
	},
	font: fontAttrs({
	editType: 'calc',
	description: [
	'Sets this axis\' title font.',
	'Note that the title\'s font used to be set',
	'by the now deprecated `titlefont` attribute.'
	].join(' ')
	}),
	// TODO how is this different than `title.standoff`
	offset: {
	valType: 'number',
	dflt: 10,
	editType: 'calc',
	description: [
	'An additional amount by which to offset the title from the tick',
	'labels, given in pixels.',
	'Note that this used to be set',
	'by the now deprecated `titleoffset` attribute.'
	].join(' '),
	},
	editType: 'calc',
	},
