Key frame speed graph won't curve correctly

Hey everyone,

I'm learning to use After Effects on my own and even though I'm an amateur I've been able to add a little pizzazz to my videos. Now I'm on the level where I want to speed up vector objects. I followed a tutorial on Youtube to a T and I'm feeling frustrated because it's so straight forward but when I do it, it doesn't do what I want it to do. Here is what I mean:

My key frames are set to easy ease. Then I go on to the speed graph and there's a grey line that I want to turn into a curve but it looks like this:

When I try to move the handles, it stays in a straight line or only makes the key frames themselves go up and down, but not curve.

What the heck am I doing wrong??

I was never taught this in school (thanks college!) and I don't have anyone I can ask for help. Any advice/instruction is greatly appreciated and I thank you in advance.
