Dear all,
sorry for this perhaps stupid question, but it concerns my recent
problem as well as the current thread on B-A plot.
I would like to plot something like x+y vs. x-y or mean(x,y) vs
difference (x,y), but my "variables" x,y are actually pairs of
replicates (two observed values of a growth rate by 60 clones). So
the order x,y does not matter and each x,y pair can be arranged
regardless the arrangement of other x,y pairs, - of course, this will
influence the appearance of the plot. I was playing with plotting
(x+y) vs. absolute value of (x-y), but this will yield plotting area
limited by the x=y line (provided the x,y are nonnegative values,
which is my case). Exists there some standard plotting procedure
for such data?
Thank you in advance!
