How can I display stacked, logarithmic bar plots in MATLAB?

I am trying to create stacked bar plots using a logarithmic scale. However, the following line of code returns a cell array:

vert=get(hb,'vertices');

This will cause an error on the next line:

vert(vert==0) = bv;

Each set of "stacked" bars is a single patch object, and the variable returned from BAR will be a vector of handles for those objects. The variable "vert" contains a cell array because each cell contains the vertices for the corresponding patch object. It is necessary to change the properties for each patch object.

for n = 1:numel(hb),

      vert=get(hb(n),'vertices');

      vert(vert==0) = bv;

      set(hb(n),'vertices',vert);    

end
