No, if they are, it is called a histogram
circle graphs add up to 100% , bar and line graphs don't
no,a bar graph is not a pictograph,pictograph's represent data by pictures and bar graphs by bars...
a circle graph is in a circular form and represents your data using pieces inside of itbar graphs represents data using bars
It doesn't matter
a bar\
the bars normally do not touch each other.
yes they can
Dual bar charts, or double bar graphs, are just like regular bar graphs, except there are two bars for each value on the x-axis.
Yes. Otherwise what is represented by the height of each bar?
In a normal bar graph, each bar represents one value. In a stacked bar graph, each bar has a number of values, stacked on top of each other. So a bar can show how a total is broken down. So each bar could represent a year, with the amounts for each month indicated by different parts of that one bar.
Some common types of graphs used in science include line graphs to show trends over time, bar graphs to compare different categories, scatter plots to display relationships between variables, and pie charts to represent parts of a whole. Choosing the appropriate graph depends on the data being presented and the message that needs to be conveyed.
Actually, they are useful. At least in some cases.
bar graphs are for measuring points of data.

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
Bar graphs provide an easy way to visualize the comparative sizes of various things. For example, let us say that you are doing something every year, you are raising money for your favorite cause. You can draw a bar for each year showing the amount you raised, and you can then see exactly what the trend may be, and how each year compares to the other years.
