To see Quadrant Linking in action, view our video on Quadrants. 
FCS Express allows you to link quadrants from one plot to another. This
means, that when the quadrants on one plot are moved, the quadrants on
the other plot will be automatically updated. This is useful in
circumstances when you want to set up a negative quadrant on your
controls, and have the quadrants on your sample data automatically
updated. In the example given below, the red data
plot will be linked to the blue data plot so when the quadrant of the blue
data plot is adjusted the quadrants on the red plot will automatically adjust.
The two plots below contain unlinked quadrants
| Quad to Quad linking allows us to link the blue plot quads to the red plot. |

The quadrants below are now linked |
