[igraph] Help with write_svg function

[Domenico Conti]

Hi, I use the following code:

 

outFolder = self.mainView.outputFolderText.GetLabelText()

fileName = outFolder+os.sep+"GRAPH_"+self.fileName+".svg"

soglia = int(self.mainView.thresholdText.GetValue())

graph.layout("kamada_kawai")

graph.es["edge_color"]=[["red", "black"][value>soglia] for value in graph.es["iFlow"]]

for vertex in graph.vs:

vertex["vertex_color"] = "green"

visualStyle = {}

visualStyle["margin"] = 20

visualStyle["layout"] = "kamada_kawai"

visualStyle["edge_color"] = [["red", "black"][value>soglia] for value in graph.es["iFlow"]]

visualStyle["vertex_color"] = "green"

graph.write_svg(fileName, layout="kamada_kawai")

but when I open svg file I can see that my visualStyle are not applied to my graph. Why?
