Color used to draw the bounding box around a cluster

type: color, default: black

If pencolor is not defined, color is used.

If color is not defined, bgcolor is used.

If bgcolor is not defined, the default is used.

Note that a cluster inherits the root graph's attributes if defined. Thus, if the root graph has defined a pencolor, this will override a color or bgcolor attribute set for the cluster.

Valid on:
  • Clusters
