The answer depends very much on the sort of data and on what information the graph is meant to convey.

It all depends on what kind of bar graph your're making, and also for what data your putting on it !
to represent and compare datas to it.
Instead of connecting points with a line, a bar graph uses bars to represent data.

A point can represent a piece of data or an (x,y) value.

There is no predetermined scale. You choose the scale so as to best represent the data.
Anytime.
A graph that has a finite or limited number of data points is typically referred to as a discrete graph. Discrete graphs represent data that can take on specific, separate values, often illustrated with distinct points rather than continuous lines. Examples include bar graphs and scatter plots, where each point correlates to a specific data value.
A pie graph represent data as a part of a whole, showing the separate portions of the data in accordance to the whole.

A concrete graph uses physical objects to represent data, such as bar graphs made with blocks. A pictorial graph uses pictures or symbols to represent data, like a graph showing ice cream sales using ice cream cones.
