 Oct 4 comment Converting imported data into a list of pairs +1 Nothing fancy. Nice and clean. Sep 18 comment Boolean value of proposition assuming previous boolean values of parts of the proposition Patrick, Why don't you post your comment as a response? I wasn't aware that Simplify could make boolean inferences. Sep 10 comment Circular Plot and Circular Histogram I used 5 and 25 bins (i.e. sectors) as examples. Aug 30 comment Calculating expected value from paired values and weights +1 Nice, clear explanation. Aug 30 comment Calculating expected value from paired values and weights Very good point. Aug 30 comment Calculating expected value from paired values and weights +1 Interesting use of Dot. It would be nice if you provided an explanation of the code. Aug 30 comment Calculating expected value from paired values and weights Thanks for pointing this out. Aug 30 comment Finding all shortest paths between two vertices It should work with weighted edges. From the documentation on GraphDistance: "For a weighted graph, the distance is the minimum of the sum of weights along any path between s and t." Jul 20 comment Is there a nice way to display big nested tables? I don't see any nesting in your table. It looks like a simple table of graphs with an ID and what appears to be an average value. Are you seriously planning to show each of these graphs to your audience without putting them to sleep? Jun 21 comment How convert list of numbers to list of points on x-axis? You may easily combine Plot and NumberLinePlot. For example, Show[{ Plot[2 Sin[x] + x, {x, 0, 15}], NumberLinePlot[{2, 4, 7, 10, 13, 6}, Spacings -> 0]}] May 31 comment Permuted Prime Numbers FromDigits[Permutations[IntegerDigits[#]]] & /@ {113, 337, 199} May 20 comment InfiniteLine Woes @MarcoB, That's just what tripped me up. And I was in an unusual hurry too. May 20 comment InfiniteLine Woes Thanks. The syntax even matches that of Line. I'm surprised I didn't try it. May 20 comment InfiniteLine Woes What about this? (from the documentation) Graphics[InfiniteLine[{0, 0}, {1, 1}], Frame -> True] Apr 23 comment Reconstruction of interrupted paths in images ImageCorners reference.wolfram.com/language/ref/ImageCorners.html may be useful for step 1. Mar 7 comment Pull out scaling factor from a denominator Algohi, That seems to be a general solution to the problem. Mar 7 comment Pull out scaling factor from a denominator Algohi, try ((2 + x)/7)[[2]] Mar 7 comment VertexLabels, EdgeLabels and the direction of the arrows on a directed graph You should be able to find solutions to all of your problems by consulting the documentation. See GraphicsGrid,VertexCoordinates, EdgeStyle, etc... Mar 1 comment Font presentation difference between version 9 and version 10 Looks fine on my MacBook with Mathematica v. 10.0.2 The font is heavier than your upper image, but far smoother than your lower image. Shouldn't Georgia be a serif font? Your lower image is sans serif. Feb 25 comment Dynamically Update both a HorizontalGauge range and the value This seems to offer more general solution (which is great because I want to add additional scales), but the lower marker sometimes jambs, sitting immobile while the upper marker is being dragged.
