First off, that's bull. There's nothing wrong w/ graphs stating clearly
that the data plotted are mean values only, maybe with rms plotted
elsewhere.
But even more important ("Zero off" ?
) Any scientist who wants to
plot quality graphs won't use Excel. He'll take the time to learn R,
or GnuPlot, or Matlab, or any of dozens of good packages aimed at real
charting.
That's bull???????
I work in science as well as hundreds of people around me and we all use
excel; where did you get you info, from Disney channel?
Customizing error bars is essential since we never get identical standard
deviations between two or more different groups of data.
These guys at Microsoft screws up on a regular basis :sillygrin:[/QUOTE]
This is an ancient post, so my response is probably lost, but:
A few points. Just because "... hundreds of people..." use Excel
doesn't mean they have a clue as to how much pain they're causing
themselves. Spend a couple hours with GnuPlot, or even the plotting
functions in R, and you'll see what real charting is about.
Error bars don't make or break a chart. It's all about how you want to
present the data, and what really matters. But if you love error bars,
and don't like the way Excel version[whichever] handles them, write
your own routines. For example, assuming you've got columns of + and -
error data, just plot them as symbols, do some gymnastics to plot lines
between pairs of points, and you're done.
