Feb 18	comment	Given a list of lists, build a list in which lists with equal first and last elements are grouped together This is cool, but could you add a little explanation of what your code does for the benefit of less experienced future visitors?
Feb 16	comment	An ancient MIDI keyboard? What have you tried?
Feb 13	comment	Styling individual bars in a BarChart with grouped data @kguler - yes, but unfortunately things like `Min`, `Max` and `FindDivisions` don't handle style-wrapped data so my custom ticks functions don't currently work :)
Feb 12	comment	Styling individual bars in a BarChart with grouped data Equivalent way to get the colors: `MapThread[ Style[#1, #2] &, {fakedata52, Outer[Blend[{{0, White}, {0.7, #1}, {1.1, Black}}, #2] &, {Magenta, Blue, Red, Orange, Green}, Range[0.1, 1, 0.1]]}, 2]`. It's worth pointing out that if you have a custom function that uses the data anywhere (e.g. calculated the `Max` and `Min` to work out ticks, you can't just pass the `Style`d data to the function. You'd need to create a `SpecialStyles` type option to that function, and combine the styles and data together in the charting function.
Feb 12	comment	Styling individual bars in a BarChart with grouped data Thanks kguler, had completely forgotten that you can style individual bars like that.
Feb 12	comment	Why is Mathematica limiting the execution time of my calculation? Have you tried adjusting `$HistoryLength`?
Feb 12	comment	How can I decimal-align tick labels at the left? Would `NumberSigns -> {"-", " "}` be even closer to what the OP wanted?
Feb 11	comment	What properties make this equation difficult to symbolically solve? Dear tumadre, welcome to Mathematica.SE! Please consider registering your account. That way, you will be able to do more on the site over time, as you accumulate reputation. Judging by these first two answers, I expect you will be accumulating more reputation before long.
Feb 11	comment	Mathematica does not evaluate my integral. Am I doing something wrong? On version 9, setting q to a number (e.g. 2) gives `\[Integral](-1 + Zeta[Log[u]/Log[2]]) \[DifferentialD]u` which isn't quite "returning unevaluated". I'm also a bit puzzled why you'd expect an analytical solution for any `q` when, for at least some values of `q<0`, there are non-zero imaginary parts in your integrand.
Feb 6	comment	How to incorporate functions within Do Loops You might find this useful: mathematica.stackexchange.com/q/7924/8
Feb 6	comment	using FindRoot in for loop Since this has been closed, I'll just mention in comments that there are some serious problems with your code. First, as ssch mentioned, the iterators don't increment. Second, you can't use A and psi both as things to be solved for and things to have values assigned to them: you may not get the expected result after running the loop once. Third, how would i and j affect the equations if they did change? You can take the definition of `q` out of the loop at least. You should also check out this question.
Feb 6	comment	How can automatic ticks be made “outie”? Congratulations on reaching 2000 rep - and on such a fun question too. +1 for the "outie" description, too.
Feb 5	comment	axis label and ticks alignment of ListPlot3D and Histogram3D Welcome to Mathematica.SE, dude! I formatted your code. See this page to find out how to do that yourself. It might help to explain what you did to “align them manually”, and what kind of output/alignment you are trying to achieve.
Feb 1	comment	Count items in a list that occur before a date Do you really need to plot every day's value? You could try `InterpolationOrder -> 0` to get your nice flat lines.
Jan 30	comment	How can I sort the elements in a 3-dimensional table? So you want to `Flatten` your list first?
Jan 29	comment	BoxWhiskerPlot - how to specify boxes position on the horizontal axis @JohnnyM - in that case, `Rationalize` is your friend. And maybe `Round`.
Jan 29	comment	BoxWhiskerPlot - how to specify boxes position on the horizontal axis @JohnnyM - you could always rescale your k's by their least common multiple so that the x-axis is integers, and then just use the `FrameTicks` option to label them as you want.
Jan 29	comment	writing a function using multiple variables Welcome to Mathematica.SE! I formatted your code for you. See this page to learn how that is done. By the way, your brackets don't match. The first one should be a round parenthesis. You should check out the answers to this question and the links from this part of the documentation.
Jan 28	comment	Finding unit tangent, normal, and binormal vectors for a given r(t) Try substituting a real number `1.` instead of exact value integer 1; another thing you can try is plotting the expression.
Jan 28	comment	Finding unit tangent, normal, and binormal vectors for a given r(t) You are most welcome. Don't rush to do this, in case you get a better answer from someone else, but it is good practice to mark the best answer you receive as "accepted" by clicking the checkmark next to it.
