I am trying to plot a graph using NetworkX draw function but
using cStringIO.StringIO(). I have read
how to do it in web2py Application Development Cookbook.
Let's say I have something like:
import matplotlib.pyplot as plt
import networkx as nx
G = nx.path_graph(8)
nx.draw(G)
plt.show()
This code plots and shows the graph. Now, to place it in a web2py view I
should use a function like:
def mygraph()
fig=Figure()
.....
.....
.....
canvas=FigureCanvas(fig)
stream=cStringIO.StringIO()
canvas.print_png(stream)
return stream.getvalue()
The problem is how to place the plot generated by nx.path_graph(8) and
nx.draw(G) in the code in
blue in order to make it work.
I am learning web2py and I am nor expert in NetworkX or matplotlib
packages. Sorry if my question
is stupid.
Thank you.
