It can be a single value, or an array for specifying color for each `link`. If `link.color` is omitted, then by default, a translucent grey link will be used. colorscales A tuple of :class:`plotly.graph_objects.sankey. link.Colorscale` instances or dicts with compatible properties colorscaledefaults When used in a template (as layout.template.dat a.sankey.link.colorscaledefaults), sets the default property values to use for elements of sankey.link.colorscales colorsrc Sets the source reference on Chart Studio Cloud for color . customdata Assigns extra data to each link. customdatasrc Sets the source reference on Chart Studio Cloud for customdata . hoverinfo Determines which trace information appear when hovering links. If `none` or `skip` are set, no information is displayed upon hovering. But, if `none` is set, click and hover events are still fired. hoverlabel :class:`plotly.graph_objects.sankey.link.Hoverl abel` instance or dict with compatible properties hovertemplate Template string used for rendering the information that appear on hover box. Note that this will override `hoverinfo`. Variables are inserted using %{variable}, for example "y: %{y}" as well as %{xother}, {%_xother}, {%_xother_}, {%xother_}. When showing info for several points, "xother" will be added to those with different x positions from the first point. An underscore before or after "(x|y)other" will add a space on that side, only when this field is shown. Numbers are formatted using d3-format's syntax %{variable:d3-format}, for example "Price: %{y:$.2f}". https://github.com/d3/d3-3.x-api- reference/blob/master/Formatting.md#d3_format for details on the formatting syntax. Dates are formatted using d3-time-format's syntax %{variable|d3-time-format}, for example "Day: %{2019-01-01|%A}". https://github.com/d3/d3-time- format#locale_format for details on the date formatting syntax. The variables available in `hovertemplate` are the ones emitted as event data described at this link https://plotly.com/javascript/plotlyjs- events/#event-data. Additionally, every attributes that can be specified per-point (the ones that are `arrayOk: true`) are available. variables `value` and `label`. Anything contained in tag `` is displayed in the secondary box, for example "{fullData.name}". To hide the secondary box completely, use an empty tag ``. hovertemplatesrc Sets the source reference on Chart Studio Cloud for hovertemplate . label The shown name of the link. labelsrc Sets the source reference on Chart Studio Cloud for label . line :class:`plotly.graph_objects.sankey.link.Line` instance or dict with compatible properties source An integer number `[0..nodes.length - 1]` that represents the source node. sourcesrc Sets the source reference on Chart Studio Cloud for source . target An integer number `[0..nodes.length - 1]` that represents the target node. targetsrc Sets the source reference on Chart Studio Cloud for target . value A numeric value representing the flow volume value. valuesrc Sets the source reference on Chart Studio Cloud for value .
