Hello Everyone,

I have below sudo code, where I need to reuse the doxygen comment in the label

/**
*  @brief Store current timestamp
**/
static UINT32 timestamp;

@dot
digraph NewGraph{
graph [nodesep="1"]
Network -> Client[ label="FG0215_PDC_timestamp", labeltooltip="\copydoc timestamp"]
@enddot

So here above in labeltooltip I want to re-use the doxygen comment of variable “timestamp”.

Please provide your suggetions or possible ways to do this.

Thansk

Go to Help - Graphviz. Click on + New Topic.

People probably wont find your reply here.

After adding the topic, it ask me “Add user”, so what user I should add here?
I have tried to add some random users, but it says that you can not add private users.

I don’t think you followed my instructions. You are trying to compose a private message, not posting a topic in the Help category.

I am considering moving from mermaid.js to graphviz but one point is still blocking me: the ability for a node to point to a cluster.

Taking the typical example everyone shows (the version, modified with my attempts is online), I tried to point the node a3 to the cluster cluster_1:

digraph G {
    compount=true;

  subgraph cluster_0 {
    style=filled;
    color=lightgrey;
    node [style=filled,color=white];
    a0 -> a1 -> a2 -> a3;
    label = "process #1";
  }

  subgraph cluster_1 {
    node [style=filled];
    b0 -> b1 -> b2 -> b3;
    label = "process #2";
    color=blue
  }
  start -> a0;
  start -> b0;
  a1 -> b3;
  b2 -> a3;
  a3 -> cluster_1;
  a3 -> end;
  b3 -> end;

  start [shape=Mdiamond];
  end [shape=Msquare];
}

The result is

cluster_1 is perceived in that context as a new node instead of the cluster labeled process #2.

Is there a way to have a node point to a cluster, without having it point to a node in that cluster? The emphasized part is important because I just know that a node points to a cluster, (and not a node in that cluster).

In other words, I cannot do, for instance,

a3 -> b0 [lhead=cluster_1];

(because that requires me to know that b0 is part of cluster_1)
