How to display median and mean on the histogram but should not overlap if same?

I am plotting some histograms but I have a small issue. If the mean and median are same then they overlap(which is perphas correct). But how can I display mean and median on the histogram but show them with arrows or dotted line. The code for plotting is as below. They are all barh plots. So the mean and median are on the Y axis.

 function usummary(x,bins,names,units)
 [p q]=hist(x,bins);
 barh(q,p)
 xlabel(units)
 ylabel(names)
 yy_tick=[min(q) mean(q) median(q) max(q)];
 yy_label={num2str(min(x)),strcat('mean = ',num2str(mean(x))) , strcat('median = ',num2str(median(x))),num2str(max(x))};

 y_tick=sort(yy_tick);
 for i=1:length(y_tick)

        j=find(y_tick(1,i)==yy_tick);
        y_label(1,i)=yy_label(1,j(1,1));

end

   set(gca,'YTick',y_tick)
   set(gca,'YTickLabel',y_label)  
  end

Also,I am still tyring to figure out how can use the nargin function in this code. Thank you so much in advance.

You can use text() to place any text anywhere you want. So set up your tick labels like you are doing now except without the mean, and then use text() to set up a label for the median just on the other side of the axis.
