How do I change the color of each bar in a plot if I do not have bar groups in MATLAB 7.6 (R2008a) ?

I use the following code to create a bar plot:
x = [46.6 -34.5 47.9];
I would like each bar to display a different color.

The following is an example of changing color of each bar by changing the color of the patches that compose the bars:
x = [46.6 -34.5 47.9]';
bhandle = bar(x);
ch = get(bhandle,'Children'); %get children of the bar group
fvd = get(ch,'Faces'); %get faces data
fvcd = get(ch,'FaceVertexCData'); %get face vertex cdata
[zs, izs] = sortrows(x,1); %sort the rows ascending by first columns
for i = 1:length(x)
row = izs(i);
fvcd(fvd(row,:)) = i; %adjust the face vertex cdata to be that of the row
set(ch,'FaceVertexCData',fvcd) %set to new face vertex cdata

Haigen MIN, in R2014b or later, in order to control the color of the bars individually, you will need to draw the bars yourself such as with using fill() or patch()
