Need help with animation XYZ axis

[wowdragon73]

Model is edited and ready for animation.
XYZ axis is centered on the object.
Trying to do a simple 360 rotation.
However when I select the auto key to set frames, the XYZ Axis moves to the bottom Left corner of the model..
How do I fix this so that the axis stays centered on the object as shown in the first picture so that I can rotate it on its center for the animation, not bottom left corner?

1. Go to the 'Command Panel' and then to the 'Helpers' tab. Create a 'Point' helper in your scene and place it at the exact spot you had intended for your object to rotate from.

2. Animate the helper to do your 360. 

3. Select your object (rock) and go to the 'Hierarchy' tab of 'Control Panel' and click 'Affect Pivot Only.' 

4. Hit 'Shift+A' and click the Point helper. Your rock's pivot point should snap to it. Now click the 'Modify' tab of 'Control Panel' to get out of 'Hierarchy' and to set things. 

5. Select your rock and go to the 'Select and Link' icon click it, and click and drag your rock so it links to the Point helper. The helper will blink once when you let go to let you know it linked. 

If you scroll the timeline, your Point pivot should now rotate your rock along with it. What's good about this is that now if you want to change how the rock rotates, you can leave the Point helper and just move the rock and change things easily. 

If you animated the Point helper properly and it's rotation like you want, then the rock should follow nicely. If not, just manually move the rock until you like the way it follows the helper.

One thing or the other, link or center pivot...

When you link some obj. to other and transform/animate it thru that (parent) obj. than it's pivot point (position/orientation) become irrelevant.

Correct @domo.spaji , but I didn't want to get into all that for now. But, @wowdragon73 , it's functionality to become familiar with.
