[reportlab-users] valuestep for categoryaxis?

[frank h.]

hm robin,
thanks for your answer
my special need is that I have *lots* of vertical bars
and I do not want a label on the x axis for each of them, as is the case now
its basically daily data over a longer period of time, plotted as bars, and
I just want to show xlabels for each week or month instead of each day (as
this becomes quite unreadable on the chart)
