How to make clear the intent of résumé status bars?

On my résumé, in order to emphasize the technologies that I am skilled with I am placing a 'status bar' along with each technology indicating a level of 1 to 5. This is the rough draft:

Is it clear that the lines are status bars? How might I make it clear that they indicate my competence levels with the various technologies?

I had originally labelled each level:

1. Hello, world!
2. I can make problems
3. I can solve problems
4. People ask me to solve problems
5. People ask me to make problems

However, with the current layout I feel that the labels just add clutter. Is there any way to integrate the labels to clarify the skill levels?

Additionally, I have in fact made sure that the status bar colour graduations gracefully degrade to greyscale for printing. Is there anything else that I should check for printing, specifically in the context of the status bars?
