plotting - BarChart frame labels


This barchart was tricky to style, and I had to resort to the legacy BarCharts`package. Any ideas how to omit the labels from the bottom edge? Ideally I'd also like separator ticks between the column pairs.


data = {{-2.8, -5.8, -7.4, -9.2}, {-3.7, -6.8, -8.9, -11.8}};


colour1 = RGBColor[82/255, 85/255, 255/255];
colour2 = RGBColor[132/255, 178/255, 255/255];

Quiet[Needs["BarCharts`"]]

BarChart[data, Frame -> True, AxesOrigin -> {0, 0}, 
 PlotRange -> {{0.525, 4.825}, {-14, 0}},
 BarLabels -> {"March", "June", "September", "December"},
 BarGroupSpacing -> 0.3, BarSpacing -> 0, 

 BarStyle -> {colour1, colour2},
 BaseStyle -> {10, FontFamily -> "Verdana"}, AspectRatio -> 0.4, 
 ImageSize -> 350]

enter image description here



Answer



Just some fun seeing how well I can dial it in by eye:


BarChart[Thread @ data,
 ChartStyle -> {colour1, colour2}, 
 ChartLabels -> {Placed[{"March", "June", "September", "December"}, Above], None},

 Frame -> True,
 FrameTicks -> {False, True}, 
 BaseStyle -> {10, FontFamily -> "Verdana"},
 BarSpacing -> {0, 0.8}, 
 PlotRangePadding -> {0.8, {2.2, 0}},
 AspectRatio -> 0.4, 
 ImageSize -> 350
]

front end - keyboard shortcut to invoke Insert new matrix

I frequently need to type in some matrices, and the menu command Insert > Table/Matrix > New... allows matrices with lines drawn between columns and rows, which is very helpful. I would like to make a keyboard shortcut for it, but cannot find the relevant frontend token command (4209405) for it. Since the FullForm[] and InputForm[] of matrices with lines drawn between rows and columns is the same as those without lines, it's hard to do this via 3rd party system-wide text expanders (e.g. autohotkey or atext on mac). How does one assign a keyboard shortcut for the menu item Insert > Table/Matrix > New... , preferably using only mathematica? Thanks! Answer In the MenuSetup.tr (for linux located in the $InstallationDirectory/SystemFiles/FrontEnd/TextResources/X/ directory), I changed the line MenuItem["&New...", "CreateGridBoxDialog"] to read MenuItem["&New...", "CreateGridBoxDialog", MenuKey["m", Modifiers-...

How to thread a list

I have data in format data = {{a1, a2}, {b1, b2}, {c1, c2}, {d1, d2}} Tableform: I want to thread it to : tdata = {{{a1, b1}, {a2, b2}}, {{a1, c1}, {a2, c2}}, {{a1, d1}, {a2, d2}}} Tableform: And I would like to do better then pseudofunction[n_] := Transpose[{data2[[1]], data2[[n]]}]; SetAttributes[pseudofunction, Listable]; Range[2, 4] // pseudofunction Here is my benchmark data, where data3 is normal sample of real data. data3 = Drop[ExcelWorkBook[[Column1 ;; Column4]], None, 1]; data2 = {a #, b #, c #, d #} & /@ Range[1, 10^5]; data = RandomReal[{0, 1}, {10^6, 4}]; Here is my benchmark code kptnw[list_] := Transpose[{Table[First@#, {Length@# - 1}], Rest@#}, {3, 1, 2}] &@list kptnw2[list_] := Transpose[{ConstantArray[First@#, Length@# - 1], Rest@#}, {3, 1, 2}] &@list OleksandrR[list_] := Flatten[Outer[List, List@First[list], Rest[list], 1], {{2}, {1, 4}}] paradox2[list_] := Partition[Riffle[list[[1]], #], 2] & /@ Drop[list, 1] RM[list_] := FoldList[Transpose[{First@li...

mathematical optimization - Minimizing using indices, error: Part::pkspec1: The expression cannot be used as a part specification

I want to use Minimize where the variables to minimize are indices pointing into an array. Here a MWE that hopefully shows what my problem is. vars = u@# & /@ Range[3]; cons = Flatten@ { Table[(u[j] != #) & /@ vars[[j + 1 ;; -1]], {j, 1, 3 - 1}], 1 vec1 = {1, 2, 3}; vec2 = {1, 2, 3}; Minimize[{Total@((vec1[[#]] - vec2[[u[#]]])^2 & /@ Range[1, 3]), cons}, vars, Integers] The error I get: Part::pkspec1: The expression u[1] cannot be used as a part specification. >> Answer Ok, it seems that one can get around Mathematica trying to evaluate vec2[[u[1]]] too early by using the function Indexed[vec2,u[1]] . The working MWE would then look like the following: vars = u@# & /@ Range[3]; cons = Flatten@{ Table[(u[j] != #) & /@ vars[[j + 1 ;; -1]], {j, 1, 3 - 1}], 1 vec1 = {1, 2, 3}; vec2 = {1, 2, 3}; NMinimize[ {Total@((vec1[[#]] - Indexed[vec2, u[#]])^2 & /@ R...
