IK show bones Degrees of Freedom I rigged a human and now want to set the limits. I have a blue / red ring that visualizes the limits on the x and z axis but not on the y axis ( I just found out that I can deactivate them by unchecking "relationship lines")

I only found this visualization of limits:

But I cant find the option to activate this in 2.78.

Thanks in advance.
To show this you need to go under the Bone properties tab and then Under the Inverse Kinematics you can set the rotation limits of the bones as shown below:

Note: Only X and Z limits will be represented in the 3d view as rotation around Y is rolling the bone around it's axis so it can't be visualised
