Bar Graph
pie chart is known as circle graph which shows a table of contents in same proportion or percentage on the chart. it is statistical graph shows a shape of pie which cut in slices. pie chart is not successfully used because it shows a single result.
Assuming both the scales on the graph are linear (that is to say that the numbers go up evenly) then YES, a graph which shows direct proportion must be a straight line. It must also pass through the origin (0,0). A straight line which does not pass through the origin is NOT showing direct proportion. Duncan
This graph states, therefore, that A is directly proportional to B. It also states that ... thus showing that this straight line through the origin represents a direct proportion. ... what you are talking about, because there are other types of proportions.
A pie or stacked bar.
Any kind of properly drawn graph does. That's what graphs do.
