plotting - How to place more than one ChartLabel in a BarChart


I have the following data:


data = {{493, 416}, {1330, 1586, 1579, 1424, 1667, 1023, 665}, {1963, 
    428, 1797, 1832, 1697, 549, 526}, {1742, 2040, 1767, 1876, 1680, 

    668, 531}, {1751, 1565, 1577, 1693, 1691, 584, 523}, {1356}};

days = {{Saturday, Sunday}, {Monday, Tuesday, Wednesday, Thursday, 
    Friday, Saturday, Sunday}, {Monday, Tuesday, Wednesday, Thursday, 
    Friday, Saturday, Sunday}, {Monday, Tuesday, Wednesday, Thursday, 
    Friday, Saturday, Sunday}, {Monday, Tuesday, Wednesday, Thursday, 
    Friday, Saturday, Sunday}, {Monday}};

daysnum = {{1, 2}, {3, 4, 5, 6, 7, 8, 9}, {10, 11, 12, 13, 14, 15, 
    16}, {17, 18, 19, 20, 21, 22, 23}, {24, 25, 26, 27, 28, 29, 

    30}, {31}};

I want to plot a BarChart and to use more than one ChartLabel. I have created a handmade picture so that you can know what I mean.


enter image description here


How can I create a ChartLabel at the x-axis and at the center and the top of the BarChart?
Is it possible to color a ChartLabel according to the Bars colors?



Answer



The problem with the following is that you are loosing the depth of the initial list data since I only found a way to do it thanks to Flatten.


data = {{493, 416}, {1330, 1586, 1579, 1424, 1667, 1023, 665}, {1963, 
    428, 1797, 1832, 1697, 549, 526}, {1742, 2040, 1767, 1876, 1680, 

    668, 531}, {1751, 1565, 1577, 1693, 1691, 584, 523}, {1356}};

(* version 8 *)
col = Cases[BarChart@data, RGBColor[__], Infinity][[2 ;;]];
(* version 9 *)
(* col = Cases[BarChart@data, RGBColor[__], Infinity]; *)

days = {{Saturday, Sunday}, {Monday, Tuesday, Wednesday, Thursday, 
    Friday, Saturday, Sunday}, {Monday, Tuesday, Wednesday, Thursday, 
    Friday, Saturday, Sunday}, {Monday, Tuesday, Wednesday, Thursday, 

    Friday, Saturday, Sunday}, {Monday, Tuesday, Wednesday, Thursday, 
    Friday, Saturday, Sunday}, {Monday}};
days = ToString /@ days[[#]] & /@ Range@Length@days;
days = Style[#, #2] & @@@ Thread[{Flatten@days, col}];

daysnum = {{1, 2}, {3, 4, 5, 6, 7, 8, 9}, {10, 11, 12, 13, 14, 15, 
    16}, {17, 18, 19, 20, 21, 22, 23}, {24, 25, 26, 27, 28, 29, 
    30}, {31}};
daysnum = ToString /@ daysnum[[#]] & /@ Range@Length@daysnum;


BarChart[Labeled[#, #2, Above] & @@@ 
    Thread[{Flatten[data, 1], Flatten[daysnum, 1]}],
  ChartLabels -> {Placed[Flatten@days, Axis, Rotate[#, Pi/2] &]}, 
  LabelingFunction -> (Placed[#, Center, Rotate[#, Pi/2] &] &),
  ImageSize -> 500, ChartStyle -> col, BarSpacing -> .2]

Mathematica graphics



About the version issue with col:


In version 8



Cases[BarChart[{{1, 2, 3}}], RGBColor[__], Infinity] // Length


4



while it apparently returns 3 in version 9.

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...
