Hi,
I'm building my first scripts with PyX trying to replace my old bash +
gnuplot scripts. Most of my work moves around plotting output from log
files that are sent to me so I can get a graphical idea of what's happening.
I want to plot graphs with time span on the x axis and numerical values
(number of transactions, number of connections, etc.) on the y axis.
This is what I have so far. Each entry from the fulldata dictionary and the
ts list have exactly the same len() and are all lists. This is an example
with the 'waittime' entry, but same thing happens with any entry of the
dictionary:
```
attrs = [color.gradient.RedBlue]
g = graph.graphxy(width=600, key=graph.key.key())
g.plot(graph.data.values(x=ts, y=fulldata["waittime"]),
[graph.style.line(attrs),
graph.style.symbol(graph.style.symbol.changesquare,
symbolattrs=attrs, size=0.1)])
g.writeEPSfile("waittime")
g.writePDFfile("waittime")
```
On running this I get the following error:
```
Traceback (most recent call last):

116, in _create
raise RuntimeError("incomplete axis range %s" % errorname)
RuntimeError: incomplete axis range for axis x
```
BTW, I had to fix the formatting in axis.py as there was a mistake which
made the `raise` not work. Where can I send patches? I'm using rpm
packages, version 0.14.1.
Any help on how to fix the error from above, or better ways to build my
graphs would be much appreciated. :-)
Kind regards, Martín
