I am able to successfully change the edge font, and the node font, but my attempts to change the cluster labels have no affect. Can someone point me in the right direction?
I have tried labelfontname=, fontname= (on the edge and the node), but can't seem to find the magic formula for cluster labels.
fontname is working for cluster labels.
Here's an example with illustration - it's quite simple, just set it before setting the content of the label.
digraph g{
node[fontname="Impact"];
subgraph cluster0 {
"Cluster node";
fontname="Courier";
label="Cluster label";
}
fontname="Arial";
label="Graph Label";
}
The result:

I am wondering if there is any library/API that can help me add a popout box to each node in the graph created by Graphviz?
I think you want the tooltip-related attributes (https://graphviz.org/docs/attrs/tooltip/). Use dot -Tsvg
digraph {
label="Graph Label"
tooltip="Graph Tooltip"
subgraph cluster_a {
label="Cluster Label"
tooltip="Cluster Tooltip"
Node1 [tooltip="Node1 Tooltip"]
Node1 -> Node2 [label="Edge" tooltip="Edge Tooltip"]
}
}
So far I tried this line but dot keeps pushing it aside making room for my nodes (pushes it to the right):
_diagram_info [shape="plaintext", label="My Diagram\l", fontsize=13]
Is there a way to center the label by pos, using dot?
That's how I'd add a title for a graph:
digraph {
// nodes, edges, subgraphs
...
// title
labelloc="t";
label="My Diagram";
}
This will add a centered title to the top of the graph.
The same syntax can also be used for subgraphs.
Before asking, I tried to search the answer for my question, buf I couldn't find.
My question is about changing edge direction in dot diagram. Rankdir is 'LR', but in certain part of graph, I want to use 'TB'. Let me give an example.
digraph G {
rankdir=LR;
size="7,5";
browser->ui_thread;
browser->db_thread;
browser->webkit_thread;
browser->cache_thread;
browser->file_thread;
browser->io_thread;
io_thread[style=filled];
cache_thread[style=filled];
ui_thread->thread[label=inherit];
ui_thread->messageloop[style=dotted];
db_thread->messageloop[style=dotted];
webkit_thread->messageloop[style=dotted];
cache_thread->messageloop[style=dotted];
file_thread->messageloop[style=dotted];
io_thread->messageloop[style=dotted];
}
it gives out graph like this
But, this is not what I want.
I want the following image. "thread" is above "ui_thread" vertically.
You may think it can be solved easily using "rankdir=same" with "thread" and "ui_thread".
I sure tried this already. but I failed. "thread" is always below "ui_thread".
thanks,
Unfortunately, graph direction can only be specified once, and the whole graph stays in that direction. In this situation, you can usually get the desired effect with a combination of constraint=false and invisible edges to force some ordering.
This code will produce your second image:
digraph G {
rankdir=LR;
size="7,5";
browser->thread[style=invis];
browser->ui_thread;
browser->db_thread;
browser->webkit_thread;
browser->cache_thread;
browser->file_thread;
browser->io_thread;
io_thread[style=filled];
cache_thread[style=filled];
ui_thread->thread[label=inherit constraint=false];
ui_thread->messageloop[style=dotted];
db_thread->messageloop[style=dotted];
webkit_thread->messageloop[style=dotted];
cache_thread->messageloop[style=dotted];
file_thread->messageloop[style=dotted];
io_thread->messageloop[style=dotted];
}
I need to print a large number of graphs using Graphviz DOT. To distinguish which input each graph corresponds to, I want to also have a caption for each graph. Is there anyway to embed this into the DOT representation of the graphs.
You can use label to add a caption to the graph.
Example:
digraph {
A -> B;
label="Graph";
labelloc=top;
labeljust=left;
}
labelloc and labeljust can be used to determine top/bottom and left/right position of the graph label.
All the details and other attributes that can be used to modify the label (font etc) in the graphviz attribute reference.
Tip: Define the graph label end of your dot file, otherwise subgraphs will inherit those properties.
Graph's can have attributes just like nodes and edges do:
digraph {
graph [label="The Tale of Two Cities", labelloc=t, fontsize=30];
node [color=blue];
rankdir = LR;
London -> Paris;
Paris -> London;
}
That dot file produces this graph.
If you are looking for a way to add a caption to a Graph object of graphviz in python. Then the following code can help:
from graphviz import Graph
dot = Graph()
dot.node('1','1')
dot.node('2','2')
dot.edge('1','2', label="link")
dot.attr(label="My caption")
dot.attr(fontsize='25')
dot.render(view=True)
Output:
When I changed the rankdir of my graph from LR to TD, my record nodes also changed their layout direction so they no longer look like a 'record'. I tried applying a separate rankdir to the nodes, but this had no effect.
How does one keep the record nodes with the correct layout?
digraph sample {
graph [rankdir=TD];
node [shape=record];
A [label="ShouldBeTop | ShouldBeBottom"];
B [label="Top | Bottom"];
A -> B;
}
Taking into account that rankdir effectively replaces the notion of "top" and "bottom" for the given graph, that's not surprising.
I am afraid that there is no easy remedy for this, save hacking the source (and that would not be easy at all). You can surround your labels in "{}" with some kind of mass search-replace solution to get the requested effect:
digraph sample { graph [rankdir=TD]; node [shape=record];
A [label="{ShouldBeTop | ShouldBeBottom}"];
B [label="{Top | Bottom}"]; A -> B;
}
You can use html table like labels instead of records. IIRC the table based labels do not rotate with the rank direction. See http://www.graphviz.org/doc/info/shapes.html#html
