Maybe because I'm still on Fedora 30. I installed the packages yesterday,
so seems that the last available version here. Plans to move to F32 are on
my TODO

Oh my! Didn't have that. And yes, ts is a list of str with the time of the
occurrence that is stored in fulldata["waittime"]

Now it fails in a completely different way. :-D

Code snippet with actual data to test:

```
ts=['13:00','13:15','13:30','13:45','14:00','14:15','14:30']

waittime = [560, 580, 540, 800, 1000, 600, 560]

attrs = [color.gradient.RedBlue]

g = graph.graphxy(width=600, key=graph.key.key())

g.plot(graph.data.values(xname=ts, y=waittime),
       [graph.style.line(attrs),
        graph.style.symbol(graph.style.symbol.changesquare,
symbolattrs=attrs, size=0.1)])

g.writeEPSfile("waittime")
g.writePDFfile("waittime")
```

```
Traceback (most recent call last):
  File "build_graf.py", line 61, in <module>
    graph.style.symbol(graph.style.symbol.changesquare, symbolattrs=attrs,
