Graph total time worked per person x nº of people

Hey all,

I'm struggling to create a graph showing the total time worked per person in two different companies.
Here is my table.

I've got the total years each employee worked for company A, B and A +B.
I want to show them all in a graph (could be a line graph, with a different line for A, B and A +B, a bar graph or any other one following the same idea).
I've created ranges to help me but it didn't really work, so I'm not sure if they are necessary.

Do you guys have any ideas about how could I handle it?

Thanks a lot!
Cheers
Beatriz
