Hi, I just started using pyx. My problem is that I get an error when all 
data values are 0. How can i draw a graph that can have all values = 0 ?
You can try this:


***************
from pyx import *

d = graph.data.list([(1, 0),
                      (2, 0),
                      (3, 0),
                      (4, 0),
                      (5, 0)], x=1, y=2)
g = graph.graphxy(width=8 )
g.plot(d, [graph.style.histogram()])
g.writeEPSfile("histogram")
g.writePDFfile("histogram")
***************
