Plot multiple stacked bars in the same plot

Hi,

I have 21 sets of bar at an axis (first image). I would like to stack each 3 of them (2nd image), hence I should get 7 sets of bar. For now, I can plot them in 7 indvidual figures. But I would like to plot them as a detached style (one plot behind another one) in the same figure. Could you please help me on this ?
