Perhaps someone else can help as I feel I am being particularly dense. for i in xrange(numcols): ax.plot([np.mean(mass[:,7]) for i in xrange(numcols)], np.arange(numcols), label=i) This gives you what I think you said, but really don't think this is what you mean as it seems a strange thing to want to do. sorry i couldn't be of more help surfcast23 wrote: > > Hi, > > there is only one column. so I want a plot of y and x.
