I don't see any extreme standard deviations in my data (i.e., the standard deviations are always less than corresponding mean values). I have replaced the lines for box / bar plot to make as line plot.

OK, a couple of things. I missed before that you were using the POSITION
keyword with !P.MULTI. That will throw EVERYTHING into chaos. You
*really* don't want to do that! Either position things with the POSITION
keyword, or let !P.MULTI do it, but don't *EVER* do both. That probably
has more to do with the plots jumping around than my earlier comments.
You have this line in your code:
> ; Fill in the error estimates
> cgColorFill, [xtime, Reverse(xtime), xtime[0]], $
> [high_error, Reverse(low_error), high_error[0]], $
> Color=colors[1], Position=position1
But, I don't see any variables named "high_error" or "low_error". Maybe
you want "var_max" and "var_min" in here? I can't be sure, because I
don't have data to play with, but I would make sure you have the
variables you are using in your code. :-)
I don't see anything wrong with your colors, except I see no reason for
this command:
cgLoadct,33,Clip=[10,245]
