 Mar20 accepted How to keep labels inside the box in BarChart3D Mar20 revised How to keep labels inside the box in BarChart3D edited title Mar20 comment How to keep labels inside the box in BarChart3D It does! @Kuba, you should post it as answer; happy to accept it. PlotRangePadding -> .35 is just perfect :) Mar20 comment How to keep labels inside the box in BarChart3D @Kuba, thanks for asking. BarChart3D rotate the labels as you change the point of view. The 3D position and overall size seem ok for very short labels as shown in first picture, but for longer labels it seems there is not enough room to display and they overflow the bottom plane. It is a little bit pedantic on my side, I am afraid, but if there is an option to change some position or size I am willing to spend some time perfecting the drawing ;-) Feb17 revised Fundamental Theorem of Calculus for definite integrals… assume continuity? added 117 characters in body Feb17 answered Fundamental Theorem of Calculus for definite integrals… assume continuity? Feb16 comment Why does Mathematica evaluate Sin[2.0] but not Sin[2]? Funnily enough, @DonComo, this N[Sin[2], 2]^2 + N[Cos[2], 2]^2 == 1 is True, although you may get a very different result in traditional programming languages. Here is what you get in Ruby (irb):  Math.sin(2).round(2)**2 + Math.cos(2).round(2)**2 == 1 => false. The reason is that Mathematica keeps track of precision and, at the level of precision requested, the two expressions are the same :) Feb16 comment Measuring fractal dimension of natural objects from digital images @VitaliyKaurov, glad you liked it. Note that Viola & Jones rightly pointed out a link between integral image and Haar wavelet basis in their paper; although this wasn't explored further. It is unclear to me the link between the paper you mentioned and fractal dimension, but certainly worth reading as I am interested in these kind of problems. Cheers.

Unexpected but interesting answer. Acknowledged as promised! Jan31 answered BarChart3D does not print zeros and odd tick positions Jan31 comment Better way to get Fisher Exact? Thanks a lot @romke-bontekoe. This is for someone who expects/needs p-values as practiced usually in medicine research, i.e. from a frequentist point of view. Do you know any support of this Bayesian view in medicine/genetics? Interestingly enough, your examples are suitable for Pearson's $\chi^2$, although the test in this context is whether one has an expected matrix having the same row and column sums as the data or not. In a Bayesian view, prior knowledge of both, row and column sums, right? Again, thanks, very interesting! Jan31 revised Better way to get Fisher Exact? Algorithm explained with an example.

Jan30 revised BarChart3D does not print zeros and odd tick positions added 35 characters in body Jan30 comment BarChart3D does not print zeros and odd tick positions @Murta, I haven't received an email to upgrade, I have 9.0.0.0 on Mac. Maybe I should contact Wolfram. Jan30 comment BarChart3D does not print zeros and odd tick positions Thanks @Mr.Wizard, I have version 9.0.0.0 and it seems behaviour changed. I am happy with my workaround tough. If you can shed light on how to place the labels I will give you the answer; my current manual placing is not portable to other NxM matrices, which is bad. Cheers!
