subgraph

[ghost]

I'm trying to join nodes to a cluster subgraph of nodes with lhead but it does not work. Here is the code I'm producing:

grViz(" digraph G {

  graph [compund = true]

  edge [color = grey,
  arrowhead = vee]

  node [shape = oval,
  label = 'Esthwaite Water',
  style = filled,
  color = aliceblue]  
  a

  node [shape = oval,
  label = 'Western Shore',
  style = filled,
  color = aliceblue]
  b
  a->b

  node [shape = oval,
  label = 'Lake',
  style = filled,
  color = aliceblue]
  c
  a->c

  subgraph cluster0 {
  node [shape = egg,
  label = '3'
  style = filled,
  color = lemonchiffon]
  d
  node [shape = egg,
  label = '2'
  style = filled,
  color = lemonchiffon]
  e
  node [shape = egg,
  label = '1'
  style = filled,
  color = lemonchiffon]
  f
  label = 'Kick Samples'
  labelloc = 'b'
  color = grey
  fontsize = 15
  fontcolor = grey
  }

  subgraph cluster1 {
  node [shape = egg,
  label = '7'
  style = filled,
  color = lemonchiffon]
  g
  node [shape = egg,
  label = '6'
  style = filled,
  color = lemonchiffon]
  h
  node [shape = egg,
  label = '5'
  style = filled,
  color = lemonchiffon]
  i
  node [shape = egg,
  label = '4'
  style = filled,
  color = lemonchiffon]
  j
  label = 'Ekman Grab Samples'
  labelloc = 'b'
  color = grey
  fontsize = 15
  fontcolor = grey
  }
  b->e[ltail=b lhead=cluster0]
  c->h[ltail=c lhead=cluster1]
  }
  ")

I've just managed to solve it, by introducing graph[compound=true] inside the subgraph {} also the main graph[] command is wrong as is not compund but compound.

Hi @TomONeillQMUL I have a similar question and hopefully you will be able to help me here:

I have created this graph and I am clustering the top half and the bottom half. Here is my code:

digraph datatracker {

    graph [compound = true]

    edge [color = grey,
          arrowhead = vee]

    # top node statements
    subgraph cluster1 {
        node [shape = box,
        fontname = Helvetica,
        width = 2, 
        penwidth = 2,
        style = filled,
        fillcolor = lightblue,
        label = A1,
        tooltip = 'A1',
        color = lightblue]
        A1

        node [shape = box,
        fontname = Helvetica,
        width = 2, 
        penwidth = 2,
        style = filled,
        fillcolor = lightblue,
        label = P1,
        tooltip = 'P1',
        color = lightblue]
        P1

        node [shape = box,
        fontname = Helvetica,
        width = 2, 
        penwidth = 2,
        style = filled,
        fillcolor = lightblue,
        label = P2,
        tooltip = 'P2',
        color = lightblue]
        P2
        P1->P2

        rank = same; P2; A1  # rank does not seem to work
        label = 'Cluster 1'
        color = grey
        fontsize = 15
        fontcolor = grey
    }

    # bottom node statements
    subgraph cluster2 {

        node [shape = box,
        fontname = Helvetica,
        width = 2,
        penwidth = 2,
        style = filled,
        fillcolor = steelblue,
        label = A2,
        tooltip = 'A2',
        color = steelblue]
        A2
        A1->A2

        node [shape = box,
        fontname = Helvetica,
        width = 2,
        penwidth = 2,
        style = filled,
        fillcolor = steelblue,
        label = A3,
        tooltip = 'A3',
        color = steelblue]
        A3
        A2->A3

        node [shape = box,
        fontname = Helvetica,
        width = 2,
        penwidth = 2,
        style = filled,
        fillcolor = steelblue,
        label = P3,
        tooltip = 'P3',
        color = steelblue]
        P3
        P2->P3

        node [shape = box,
        fontname = Helvetica,
        width = 2,
        penwidth = 2,
        style = filled,
        fillcolor = steelblue,
        label = P4,
        tooltip = 'P4',
        color = steelblue]
        P4
        P3->P4
        A2->P4

        node [shape = box,
        fontname = Helvetica,
        width = 2,
        penwidth = 2,
        style = filled,
        fillcolor = steelblue,
        label = P5,
        tooltip = 'P5',
        color = steelblue]
        P5
        P4->P5

        node [shape = box,
        fontname = Helvetica,
        width = 2,
        penwidth = 2,
        style = filled,
        fillcolor = steelblue,
        alpha = 0.5,
        label = AP,
        tooltip = 'AP',
        color = steelblue]
        AP
        P5->AP
        A3->AP

        rank = same; P4; A2 # rank does not seem to work
        label = 'Cluster 2'
        color = red
        fontsize = 15
        fontcolor = red 
    }
}

This produces the following figure:

However, what I am trying to achieve is the rank of P4 and A2 should be same as well as A1 and P2 should be at the same rank such that the graph looks like this:

Also not sure how to reconfigure the plot so that As are on the left and Ps are on the right. Can you help me?
