A pie chart or composite bar graph.
In a normal bar graph, each bar represents one value. In a stacked bar graph, each bar has a number of values, stacked on top of each other. So a bar can show how a total is broken down. So each bar could represent a year, with the amounts for each month indicated by different parts of that one bar.
There is no vertical bar in a fraction. A fraction is written with either a horizontal bar or a slanted bar, which is technically called a "vinculum", but most people call it a "fraction bar".

The bar is a rigid straight finite object that is attached to one fixed point. The bar can be moved but the point where it is attached must stay where it is. In theory, therefore, the bar can be rotated around that fixed point in any direction. At the level of mathematics that your question suggests, the bar is movable in only one plane.
A pendulum is made up of a stiff bar that moves freely on a fixed point. The bar is attached to a pivot point and swings back and forth due to gravity acting upon it. Pendulums are commonly used in clocks and scientific experiments to measure time or gravity.
A lever is a simple machine but it is made out of a stiff bar that moves freely around a fixed point.

A lever. It is a simple machine that consists of a rigid beam or bar that is supported at a fixed point and used to transmit force, typically to lift or move objects. The fulcrum is the point at which the lever pivots.
The fixed point where a lever pivots is called a fulcrum.
