| 2 | +Partial camera linking |
| 3 | +====================== |
| 4 | +
|
| 5 | +You can customize the camera axes that a controller acts on. In this example with two subplots you can pan and zoom |
| 6 | +in x-y in each individual subplot, but only the x-axis panning is linked between the two subplots. The y-axis pan |
| 7 | +and zoom in independent on each subplot. |
