Hi Yannis, As the error message states, that is happening within your code at line 459. It isn't going down to graph_tool or graphviz. And it is a python NameError for 'label', so you're simply using a name 'label' that is not defined. You can't define a dictionary using as argument something that is not defined. In this case it is your dictionary definition that should have quoted the name so it becomes a string. Try this instead: graphviz_draw(g, vcolor=typev, vprops={"label": labelv}, eprops={"label": labele}, output=fname+".pdf") Good luck, ale On Thu, Oct 15, 2015 at 8:46 AM, Yannis Haralambous <yannis1962@gmail.com> wrote:
Sorry for disturbing again, but I’m trying to draw a graph (with graphviz) with labels on vertices and on edges. I saw in the documentation that vprops and eprops are Python attributes with values that are dictionaries containing key-value pairs, where key is a graphviz attribute and value is either a string or a property map.
So I tried the following:
*graphviz_draw(g, vcolor=typev, vprops={label: labelv}, eprops={label: labele}, output=fname+".pdf »)*
where label is a graphviz property (as explained in http://www.graphviz.org/doc/info/attrs.html#d:label) and labelv and labele are property maps defined as
*labelv = g.new_vertex_property("string")labele = g.new_edge_property("string »)*
This doesn’t work and I get the error message
*Traceback (most recent call last):* * File "build-graph.py", line 459, in <module>* * graphviz_draw(g, vcolor=typev, vprops={label: labelv}, eprops={label: labele}, output=fname+".pdf")* *NameError: name 'label' is not defined*
But label is indeed a graphviz property, no doubt upon that. What am I doing wrong?
Thanks in advance
Yannis
