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.
legend>
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.
A pie graph represent data as a part of a whole, showing the separate portions of the data in accordance to the whole.
Bar graph
This graph is called the x graph.
Every graph must have a key. Keys are to show which bit of the graph represent which data and what values are shown by the location or size or colour of the graph.
Any type of graph is a pictorial representation of data values. A continuous line graph, such as a curve or a parabola, may represent a variable equation.
Probably a pie (or circle) graph.
line graph
There's a bar graph, pie graph, and a line graph. All represent amounts of change or amounts of a substance. Hope this helped
Bar graph for amounts. Histogram for amounts over a certain amount of time.
A line graph.
