In two main situations:
1. When there are so many observations that the bars would be extremely thin, and also differences in class widths are no longer of great importance.
2. When you wish to compare two (or more) "dependent" variables, and if plotted as bars, one would hide the other.
What else can I help you with?
What type of graph would you use for comparisons?
line or bar graph
What graph would you use to show monthly temperature for the year?
You can use a bar graph or a line graph.
What type of graph do you use when you are comparing things that is not a double bar graph?
you would use a line graph
Why would you use a broken line graph?
You would use a broken bar graph, when grouping and gathering information. You would use straight, slanted, or vertical lines and showing points with dots. A broken bar graph is just like a line graph.

I'm in sixth grade and I use circle graphs in social studies and bar and line graphs in science
The best graph to use if I want to compare the price of six different cars would be a?
Gay
How would you tell what type of graph you use?
You usually want to use a bar graph. If you have a year of data you probably want to use a line graph.
What is the best use of a line graph and what is the best use of a bar graph?
a bar graph is best used for comparing amounts, a line graph best represents a steadily increasing value. For example prices of a shirt (line graph), or viscosity of liquids (bar graph).
What type of graph would you use to show comparisons?
Bar charts are good for comparing related items. Answer: for Excel it is best known as a column chart.
Which graph do you make a line or bar graph when your science project is about which wrapping will keep the apple slice fresh from rooting?
You would use a bar chart. A line graph is for showing stuff like temperature.
When do you use a line graph and when do you use a bar graph?
Bar graphs are used when graphing a qualitative independent variable, but a line graph is used when the independent variable is quantitative. Also when you are comparing quantity of objects(bar graph)
Would you use a bar graph to track costs in a small retail shop?
You could, but a line graph would probably be better.
