------- Additional comments from [EMAIL PROTECTED] Wed Apr 12 06:05:05 -0700 2006 ------- You are completely right, that the program calculates a variance of the whole data set and displays the variance of all data results for all data points by taking aech point as mean for the variance. The problem is that I don't know anyone who really needs this particular statistical graphics. The common requirements for data series are the following 1. you have a pool of data measured at one time point (such as in the column of the example) then you usually (if at all) show the points in one row. i.e. one !above! the other and add the calculated variance in the same row. 2. you have a set a data for different time points than you calculate the mean and variance or median and percentile for each time point and display the results along the time axis (such as in the graph of the example). In this case the the variance differs from time point to time point along the X-axis. You need such presentation for scientific data or the representation of stock values where you have a min/max or variance of the day or a time point of measurement and display it along the time axis 3. in case of a quality control chart you quantify the variance over all data of a time series but the representation of the variance is not displayed by taking each point as a mean showing the variance value for this point value but you show a two line band by taking the gobal mean (mean of all data points) and display each data point relative to this lines. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
