Ah, yes, I should have added that I have a lot of them, so this seems like improper usage. I found the collections.LineCollection class which sounds like what I want.

Thank you for the help,

You can plot them all individually; e.g.

rec = ([1,2,.5], [0.5, 3, 1.1], [5, 7, .2])
for r in rec:
   pylab.plot( r[:2], [r[2]]*2)

I have a set of records with (start, end, value) values. Basically they represent "we had this value between these two times". The end of one record is not necessarily the end of another record.

I would like to plot a set of line segments with end points (x=start, y= value)  and (x=end, y=value), so I will have time on the x axis and value on the y axis.

Does anyone have any ideas on how I could do this? I would really like my line segments not to be connected, so I don't want to use a line plot or xyplot.
