Oops, yeah, in fact it defined the \Sun symbol. However, I get another
error which I don't get (apparently it is a problem exporting the graph as
EPS, i.e., it crashes at the g.writeEPSfile("testhistogram") line):
raise RuntimeError("missing font information for '%s'; check fontmapping
file(s)" % self.name)
RuntimeError: missing font information for 'mathb7'; check fontmapping
file(s)
