MATLAB: Barh with colored bars: differences between 2012b and 2014b

barhfacevertexcdatar2014bgraphics

hi,
I have a problem with the function barh when upgrading from MATLAB 2012b to MATLAB2014b.
I have the following function
function [ h ] = barh_colored(phi,cmin,cmax,loglinear)
%UNTITLED Summary of this function goes here
%   Detailed explanation goes here
  nbars2 = 64;
  if cmax ~= -1
      xbars=cmin:(cmax-cmin)/(nbars2-1):cmax;
      [counts,x] = hist(phi, xbars);
  else
      [counts,x] = hist(phi, nbars2);
  end
  if strcmp(loglinear,'log')
      h = barh(x,log10(counts),1);
  else
      h = barh(x,counts,1);
  end
  set(gca,'YAxisLocation','right');
  ch = get(h,'Children');
  fvd = get(ch,'Faces');
  fvcd = get(ch,'FaceVertexCData');
  cmap=get(gcf,'Colormap');
  colormap(cmap);
  for i=1:nbars2
      fvcd(fvd(i,:))=i;
  end
  set(ch,'FaceVertexCData',fvcd)
  if cmax ~= -1
      ylim([cmin cmax]);
  end
end
This code works fine with MATLAB 2012b. It generates plots like this:
Recently I switched to MATLAB 2014b and the code does not work anymore. Reason is that barh object does not have Children anymore so that:
ch = get(h,'Children');
returns an empty GraphicsPlaceHolder object.
How can I solve this?

The Bar properties of Children is no longer available.
This is along the lines of what you want to accomplish:
bar([1 nan nan], 'facecolor',[1 0 0])
hold on
bar([nan 2 nan], 'facecolor',[0 1 0])
bar([nan nan 3], 'facecolor',[0 0 1])
hold off
