Im a little unsure how to make a hud like this

Each of the colors is a meter and must increase and decrease. The blue, black and green. The white part is either going to be a tranparent space or just white, the blue bar has not filled it in yet.

Do you have any suggestions on how to make a meter like this?
Ill be looking into some examples but the best way to learn is from someone who has done it before.
