ArcDiagramChart: Blazor arc diagram chart component

Examples

Basic

Each GraphLink joins two node names with a Value; nodes appear in order of first mention and grow with their number of links.

Shared tickets between teams

Groups and order

Nodes gives each node a Group (colour and legend); Sort="Group" places each group side by side so links inside a group stay short.

API

<ArcDiagramChart>

DaisyBlazor.Charts

Parameters

AspectRatio double
= 1.78
Width divided by height. The chart keeps this shape at any width; its text keeps its size.
GroupColors IReadOnlyDictionary<string, string>
= null
Optional colour per group name (any CSS colour); other groups cycle through the theme palette.
Links IReadOnlyList<GraphLink>
= []
The connections. Node names come from Source and Target; links to the same node or without a positive Value are skipped.
Nodes IReadOnlyList<GraphNode>
= null
Optional node list: sets the order and each node's Group (its colour), and adds nodes that have no links.
RowHeight double?
= null
Height of each row in px, for a chart that lays its categories out as rows (horizontal bars, a Gantt's lanes, a heatmap's rows…): its height then follows its number of rows instead of AspectRatio, so a long list keeps readable rows at any width. A chart, or an orientation, without rows ignores it.
ShowLegend bool
= true
Show a colour key for the node groups under the chart.
ShowTitle bool
= true
Draw Title as a visible heading above the chart (the default); false keeps it only as the chart's accessible name, for a chart inside a card that already has a heading.
Sort ArcDiagramSort
= ArcDiagramSort.Input
How the nodes are ordered on the baseline.
Title string
= null
Optional heading rendered above the chart; it is also the chart's accessible name.
ValueFormat string
= "{0:#,0.##}"
Format string for link values in tooltips, e.g. "{0:N0} calls".
Width string
= "100%"
CSS width of the chart wrapper.
Class string
= null
Additional CSS classes merged onto the w-full wrapper.
Style string
= null
Inline styles appended after the width on the wrapper.
