Categories label is not fit in Matlab GUI

I have design a GUI which cannot show categories in barh? Can anyone guide?

            c = {'Triangle','Square','Round'};
            triangle=66;
            squre=23;
            round=11;
            total=triangle+squre+round;
            percentage = [triangle/total squre/total round/total].*100; 
            set(handles.axes1,'Visible','on');
            cla(handles.axes1,'reset');
            axes(handles.axes1)
            barh(percentage)
            set(gca,'yticklabel',{c{:}})
            axis off

Here is the output
