Problem of Plot Results with Command Recorder

Hi Tiago, 

Thanks a lot for the great tool!

I found that Plot Results causes several warnings when it is used while the command recorder is running (with "macro" selected). These warning seems to be caused by the redundant in label names of checkboxes for X and Y axes. I paste the warnings in below. 

I added underscores and explicitly stated X or Y for each label to avoid this warning. Generic dialog looks clumsy with many "X"es and "Y"s so it could be solved in some more neat way... but to tell you the problem, I pull-request. Solution does not have to be this way. 

When additional plot is added, more warnings concerning redundancy in keys 'x-values' and 'y-values' pops up. I did not do anything with this problem, I do not have idea. You might have a better solution for this.

Cheers, 
Kota
