Interface: ChordTraceLink

The links: ribbons between the arcs.

Properties

Property	Type	Default value	Description
arrowlen?	number	0	With directed: length of the arrowhead the target end of every ribbon is drawn as, in CSS px; 0 draws the ends flat. Minimum: 0
color?	PerPointColor	undefined	Ribbon color, or one per link. Default: the color of a node of the link (link.colorsource).
colorsource?	"source" | "target" | "gradient"	"source"	Which node a ribbon without a link.color takes its color from: its 'source', its 'target', or both ('gradient': from the source's color at one end to the target's at the other, in steps along the ribbon).
customdata?	DataColumn	undefined	Extra data per link for %{customdata} and events.
gap?	number	2	Space between the ring and the ends of the ribbons, in CSS px. Minimum: 0
hovercolor?	PerPointColor	undefined	Ribbon color while it (or a node it connects) is hovered, or one per link. Default: the ribbon color, a quarter more opaque. The other ribbons are dimmed meanwhile.
hoverinfo?	"all" | "none" | "skip"	"all"	Hover of the ribbons: labels ('all'), highlighting without labels ('none') or no hover and no events ('skip'). Default: the trace hoverinfo.
hovertemplate?	string	undefined	Template of the link hover labels: %{label}, %{value} (formatted with valueformat and valuesuffix), %{reverse} (the flow back, for a pair of matrix cells drawn as one ribbon), %{percent} (share of the total flow), %{source.label}, %{target.label}, %{color}, %{customdata}. <extra>…</extra> replaces the value box.
label?	DataColumn	undefined	Link labels, shown in hover labels.
opacity?	number	0.6	Opacity of the ribbons (multiplies their color's own). Range: 0 – 1
sort?	"input" | "value" | "position"	"position"	Order of the ribbon ends within an arc. 'position': by where the other end of each ribbon is on the ring, which crosses the ribbons as little as possible. 'value': widest first. 'input': by link index.
source?	DataColumn	undefined	Source node index of every link.
target?	DataColumn	undefined	Target node index of every link. A link from a node to itself is drawn as a hill on its arc and takes its value of the arc once. A link whose source or target is not a node index is left out and counted in the description.
targetgap?	number	undefined	With directed: space between the ring and the target end of the ribbons, in CSS px. A larger gap than link.gap shows the direction: ribbons touch their source and stop short of their target. Default: link.gap. Minimum: 0
value?	DataColumn	undefined	Flow of every link, which sets the width of its ribbon at both ends. Default: 1 for every link. When given, links without a positive value are left out and counted in the description.
