I also get such error when I try to plot:

/home/chia/YADE-r2039-law/lib/yade-bzr2039/py/yade/__init__.pyc in plot()
    105                         if y1: plots_p_y1.append(d)
    106                         else: plots_p_y2.append(d)
--> 107
plotLines[p]=pylab.plot(*sum([[data[p],data[d[0]],d[1]] for d in
plots_p_y1],[]))
    108                 pylab.legend([_p[0] for _p in
plots_p_y1],loc=('upper left' if len(plots_p_y2)>0 else 'best'))
    109                 pylab.ylabel(','.join([_p[0] for _p in plots_p_y1]))

KeyError: 'step'

Is there any particular reason? How is it that for you is working? Is that
up to me or to the release I am using?

Thanks, Chiara
