Hello , I have generated a bar graph. I want that each of my 6 bars must show its corresponding value and point on it. How can I do so? I am sending my code.

if true
  y=[106.59 84.800; 106.59 90.75; 106.59 90.92]
x=categorical({'A1 B1','A2 B2','A3 B3'})
bar(x,y)
xlabel('cases')
ylabel('energy cost (Rs.)')

end
