Hi Jeff Pang and Tom Phoenix, Thank you both very much. What I want is just like Figure 1: Histogram and the Normal Distribution for PCC Compressive Strength Data in http://training.ce.washington.edu/WSDOT/Modules/08_specifications_qa/normal_distribution.htm (I don't know how I can post picture here.) I have a series data and want to get a bell curve from this data with perl. I searched in http://search.cpan.org/ before I posted here. But I can't find the example. Jeff's suggestion can create splined (smoothed) line graphs. I think this isn't a bell curve. Am I right? Can you both give me more advice and example?
