------- Additional comments from [EMAIL PROTECTED] Tue Sep 19 00:37:20 -0700 2006 ------- Hi, Ingrid. This is a restatement of issue 69423 as requested. It is common in science to show graphs with number of counts in the ordinate. When these counts reflect statistical variation around a constant rate, the distribution is Poisson, and is well approximated by a normal distribution with standard deviation given by the square root of the ordinate value. This should be very straight-forward to code by copying the code used to produce % error bars. While suplying error bars from a range (766) is a long-standing request which would aloow the user to do this, 766 has been delayed for years presumeably for technical reasons. Including one of the common error estimates is a useful simplification of a common case, and should not suffer the 766 delays. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
