They are best for showing sets of data that just have an amount. This usually happens with a survey.
bar graph
the best time to use a bar graph is when you have to plot something
line graphs are usually the most best way to present data. sometimes i use pie graphs or bar graphs, but usually line graphs are the most meaningful.
b the pie graph is circle ok
Bar graphs are used to display countable data that are grouped in categories.
bar graph
Line graphs are the best graphs in order to display differences in data over time because the trends (if any) are easy to point out, as opposed to a bar graph, which deals with categorical data, or a pie chart, which deals with relative frequency.

Bar graphs, line graphs, and pie charts Bar graphs, line graphs, and pie charts
bar graphs are for measuring points of data.
circle graphs add up to 100% , bar and line graphs don't

well...not sure if you know this but bar graphs already ARE bar graphs, the good news is you don't have to transform them... so half your work is already done XD!

Line graphs and Bar graphs
Both bar graphs and picture graphs show statistics (data) in a visual (graphic) form.
