You can either normalize all the axes so that they fit within the same scale on a common axis and plot the data in different colors. This is far easier. You just give the legend of the data different scale, and that's just as presentable as having 3 set of tickmarks
Or you can use ha=axes('Position',[x y width height]) commands manually to set 2 axes to coinside in position as the primary axis, and plot data using plot(ha,datax,datay) on all 3 of them. You need to set the axis backgrounds to transparent on the 2 latter axes, as well as remove tick marks if desired. This is not as nice as resizing figure window may cause problems.
