Multiple figures of varying sizes into a single figure

I have 3 figures (of varying sizes) generated from 3 functions I wrote, and each generated figure is of very different size, customized to best display the graph/statistics.

See the sample outputs below:

generateFigure1(data)

output:

generateFigure2(data)

output:

generateFigure3(data)

output:

I would like to have a master figure which includes all of the three figures like below, keeping the sizes of original figures:

I have tried,

subplot(3,2,1) 
generateFigure1(data)
subplot(3,2,2)
generateFigure2(data)
subplot(3,2,5)
generateFigure3(data)

And figures overlap one another completely.. any help would be greatly appreciated!

Within each subplot try altering the axis 'Position' property - this doesn't just move the position but also can change the size. For instance

subplot(3,2,1) 
generateFigure1(data)
subplot(3,2,2)
generateFigure2(data)
ax = gca;
ax.Position = [0.5 0.3 0.4 0.2]
subplot(3,2,5)
generateFigure3(data)

will alter the position and size of figure 2.
