First chapter first pages, the histograms... In Roassal they were not working so well.
So lately I restructured the RTDistribution package. This, by default make a classical frequency distribution, with an optimized number of classes. The method #strategyBlock: allows to change the strategy for the distribution.
I also worked on the RTHistogramSet and method #histogram of SequenceableCollection to improve a bit the looking. There is still here some work to do but at least the histogram works well and looks fine.
We worked with Alejandro on the algorithm of frequency distribution to make it efficient compared to the classic one (Only one iteration on datas during the algo itself).
Here are some examples, don't hesitate to try a bit and give me feedbacks if any bugs, so I can move on the next graphs ;)
#(5 3 8 6 5 4 2 9 1 2) histogram.
#(1 2 3) histogram.
#(555 1 1 2) histogram.
((1 to: 1000) collect: [:i | i atRandom ]) histogram.
