Sorry if I was not clear, let me try to be clearer. Sure, I understand the concept of adding more outliers, but I want to add points that are not one of the predefined data points (ie. not lower, upper, Q1, Q3, mean, median or outliers). So. I want to add, to the example above, a point representing 69 in January. I do not want it to appear as an outlier (with an X symbol).
Also, the NIST link on http://www.telerik.com/help/windows-8-html/chart-boxplot-series.html needs to end in .htm
