Strange Behavior in Barchart LabelingFunction

The maximum number of labeled bars in Version 10.0.0 seems to be limited to 99 when LabelingFunction is used. An alternative work-around is to wrap data with Labeled:

RandomSeed[1]
barchart2[n_,m_]:=  Module[{dt=RandomInteger[10,{n,m}]},  
       BarChart[Labeled[#,#,Center]&/@#&/@dt,
                AspectRatio->0.2,ImageSize->700,
                ChartLayout->"Percentile" ]]

barchart2[34,3]

barchart2[50, 5]

A workaround is just to use multiple bar charts for the data

RandomSeed[1];
Clear[barchart];
barchart[n_, partitions_: 1] := Module[
  {m = Ceiling[n/partitions]},
  BarChart[
      #,
      LabelingFunction -> (Placed[#1, Center] &),
      AspectRatio -> 0.2,
      ImageSize -> 700,
      ChartLayout -> "Percentile"] & /@
    Partition[
     Join[
      RandomInteger[10, {n, 3}],
      Table["", {m - 1}]],
     m] //
   Column]

barchart[33]

barchart[51, 2]

The behavior was corrected in Mathematica 10.0.1.

Using the same example:

    RandomSeed[1]
barchart[n_]:=
    BarChart[RandomInteger[10,{n,3}]
            ,LabelingFunction->(Placed[#1,Center]&)
            ,AspectRatio->0.2,ImageSize->700
            ,ChartLayout->"Percentile"
    ]

barchart[33]
barchart[100]

We now have:

My tks to Wolfram team!
