Node marks are colored concentric circles around nodes. They are created by:
m -t <time> -n <mark name> -s <node> -c <color> -h <shape> -o <color>and can be deleted by:
m -t <time> -n <mark name> -s <node> -XNote that once created, a node mark cannot change its shape. The possible choices for shapes are, circle, square, and hexagon. They are defined as lower-case strings exactly as above. A nam trace showing node mark is:
m -t 4 -s 0 -n m1 -c blue -h circleindicating node 0 is marked with a blue circle at time 4.0. The name of the mark is m1.
