MATLAB: Bar series plot, transparent colors on the bars

barseriesforlooppatchestransparent

I use Matlab v. R2014b and have a problem with setting the bar series plot to have transparent colors. I add 9 different data sets (given by a&b) on one single plot/figure, using a for-loop and the hold on comand. A simplification of the code is given here:
————————————————————-
plotStyle = {'b','k','r','g','c','m','y',[1 0.270588 0],[0.180392 0.545098 0.341176]}; %setting colors for the plot
for i=1:9 %starting for-loop
 a=[1; 2; 3; 4; 5]; %vector giving moment, x-axis
 b=[10; 3; 5; 7; 9]; %vector giving number of occurences, y-axis    
 z=rand();
 a=a.*z;
 b=b.*z;
 % Both a & b is updated for every round of the loop, here exemplified with use of a random number
 figure (1)
 bar(a,b,'FaceColor',plotStyle{i},'EdgeColor',plotStyle{i});
 legendInfo{i} = ['Overpull' num2str(i)];
 hold on
end %ending for-loop
legend(legendInfo) %displaying legend
—————————————–
To get transparent bar I therefore tried to add "FaceAlpha" in the "bar-command", but this is not allowed for barseries as far as I have found out. I have also tried using handles with pathces, but this doesent seem to work with this version of matlab… Does anyone have a solution on how to get transparent colors on the bars?

Try the solution I have pasted in another post ... just last night. I have made a function which creates the patches necessary to create a transparent bar plot.
