示例1: as_graph
# 需要导入模块: from pygraphviz import AGraph [as 别名]
# 或者: from pygraphviz.AGraph import write [as 别名]
def as_graph(self, to=None):
from pygraphviz import AGraph
g = AGraph(directed=True)
for a in self.activities.values():
g.add_node(a.title, label=a.title)
for t in self.transitions.values():
g.add_edge(t.input.title, t.output.title, label=t.name)
if to:
g.write(to)
else:
return str(g)示例2: draw_graph
# 需要导入模块: from pygraphviz import AGraph [as 别名]
# 或者: from pygraphviz.AGraph import write [as 别名]
def draw_graph(state_manager, filename):
graph = AGraph()

graph.node_attr["shape"] = "circle"
graph.node_attr["fixedsize"] = "true"
graph.node_attr["width"] = 0.5
graph.node_attr["height"] = 0.5
# we add all nodes (keys = ID)
graph.add_nodes_from(state_manager.state.keys())
for var_id in state_manager.state:
# and for each of these nodes, we change color
node = graph.get_node(var_id)
node.attr["fillcolor"] = get_color(state_manager.state[var_id])
# finally, we add edges
for c in state_manager.constraints:
e = c.list_vars
graph.add_edge(e[0], e[1])
