Graph Data Outline Dissapearing

[tryingtoexcelatexcel]

Hi All,

I have a very basic question that i cant seem to figure out. When I click on my graph I can see the outline for X, Y and Data. But when I move my mouse to re-adjust the data it won't let me. The lines dissapear and I can't seem to drag the boxes to adjust them.

Any idea how to fix this? Very weird.
