How do I get the animation paths in the graph editor to match?

Question Animation

I want to get the spacing the same with the ball traveling down to match the spacing going up. I am using the Graph editor and scaling the handle to match frame 11, but when I do this it will not match frame one. What can I do to make the up and down animation path identical?

    Hi CCWieland ,

    I think you made a mistake in counting: Frame 1 is up, Frame 12 is down, that would mean the next top is on Frame 23 (you have it on 24) and the next down on Frame 34 (you are on 35)....

    Hi -  I know Martin answered your question, but this might help in the future.  You can set the handle values using using F-Curve in the graph editor.

    Also it is sometimes easier to just work with the motion paths, to try to get the motion you. want.

    Also if you want a keyframe to be the same in a given frame number, you can also Shift + D in the timeline to duplicate the frame and with G to grab, enter the number of frames you want that moved and they will be identical.

    Thanks you all, I appreciate the help. I am going to screen record to show you what I am attempting to do. I think that is the best way to ask.

    Hi CCWieland ,

    If you match the handles exactly, then you get what you want, but there are three keyframes that can influence the curve:

    I think that your handles on keyframe 1  are not symmetrical/matching keyframe 25. If you have perfect symmetry in all your handles around frame 13, then the curves will also be symmetrical and therefore the Motion Path will match.
