penwidth

type: double, default: 1.0, minimum: 0.0

Specifies the width of the pen, in points, used to draw lines and curves, including the boundaries of edges and clusters.

penwidth value is inherited by subclusters, and has no effect on text.

Previous to 31 January 2008, the effect of penwidth=W was achieved by including setlinewidth(W) as part of a style specification.

If both attributes are set, penwidth will be used.

Valid on:
  • Clusters
  • Edges
  • Nodes
