You need to control the AspectRatio of the charts.
Needs["Graphics`Graphics`"]
m = 3; n = 2;
DisplayTogetherArray[
{Plot[x, {x, 0, 10}, AspectRatio -> (n/m)/3]},
{Plot[x^2, {x, 0, 10}, AspectRatio -> (n/m)/3]},{Plot[E^x, {x, 0, 10},
AspectRatio -> (n/m)/3]},
ImageSize -> 200*{m, n}];
For different sizes:
Show[Graphics[{
Rectangle[{0,1},{2,2},
Plot[x, {x, 0, 10}, AspectRatio -> 1/4,
DisplayFunction -> Identity]],
Rectangle[{0,0},{1,1},
Plot[x^2, {x, 0, 10}, DisplayFunction -> Identity]],
Rectangle[{1,0},{2,1},
Plot[E^x, {x, 0, 10}, DisplayFunction -> Identity]]}],
DisplayFunction -> $DisplayFunction, ImageSize -> {600, 400}];
For inlays:
Show[Graphics[{
Rectangle[{0,0},{2,2},
Plot[x, {x, 0, 10}, DisplayFunction -> Identity]],
Rectangle[{0.1,1.1},{1,2},
Plot[x^2, {x, 0, 10}, DisplayFunction -> Identity]],
Rectangle[{1.1,0.1},{2,1},
Plot[E^x, {x, 0, 10}, DisplayFunction -> Identity]]}],
DisplayFunction -> $DisplayFunction, ImageSize \[Rule] {600, 400}];
Using two y-axes is an FAQ and someone will provide the URL for the answer at
the Mathematica site.
