Hi everybody:

I'm utterly frustrated: I have lost a piece of code (I think it was by Viann Beadle or perhaps Jon Peck) . Some months ago, trying to help someone I finally got my computer infected with a darn Bagle virus. The cleaning process was like a tidal wave (reformatting hard drive and installing everything back), and some files were forgotten behind or unrecoverable: old mail and some syntax files I had left in a temporary folder. As a result, I am missing a piece of syntax to plot a bivariate centroid plot. I hadn't realized until today (because I need it, of course). I have tried to fiddle with GPL syntax, but I have been defeated (I'm really not good at graphs). I have also been searching the archives, but, I can't remember how I asked the question (I tried to search by: centroid, bivariate plot (or graph), error bars... without any success). Perhaps the message subject was strange, or the name centroid wasn't mentioned at all... I remember I also got an Excel solution (which also, alas!, lost).

Sorry I have to ask again

* This is the dataset * DATA LIST LIST/group (F8) gluc trigl (2 F8.2). BEGIN DATA 1 5.17 1.51 1 5.25 1.64 1 5.31 1.59 1 4.58 1.52 1 5.56 1.64 1 5.15 1.35 1 5.33 1.68 1 5.29 1.30 1 5.01 1.91 1 5.88 1.30 2 4.92 1.32 2 4.71 1.41 2 4.79 1.24 2 4.04 1.24 2 4.82 1.39 2 4.41 1.32 2 4.89 1.36 2 4.60 1.33 2 4.75 1.20 2 5.33 1.41 2 4.67 1.18 2 4.08 1.37 2 5.19 1.28 2 4.77 1.05 2 4.94 0.99 2 4.65 1.31 2 4.76 1.29 2 5.33 1.20 2 4.70 1.18 2 5.02 1.13 END DATA.

* This is the goal: a centroid (meanx/meany) plot with SD as error bars *.

Mad at myself, Marta
