Hi Chris,
well it seems this feature is not implemented. I'm also not sure if it is even
possible in a sane way.
However if you are using graph.style.text together with another style, you can
try the following:
class mytextstyle(graph.style.text):
def key_pt(self, privatedata, sharedata, graph, x_pt, y_pt, width_pt,
height_pt):
pass
# [your code]
# then use mytextstyle instead of graph.style.text
g.plot(data, [graph.style.line(), mytextstyle()])
This should provide a key where the style is determined by the linestyle and
text has no influence.
Gruß,
Stefan
