类别标签不适用于Matlab GUI

Question

我设计的GUI无法在barh中显示类别？谁能指导？

        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

这是输出
