There are two main purposes. One purpose is for pattern recognition. Humans are very good at recognising patterns such as [linear] trends, cyclical patterns, clusters and so on. This is useful for preliminary investigation of data.
The second purpose is to illustrate summary data in a quick-and-easy way.
a bar graph is a graph that displays data using bars and a line graph is a graph that displays data in a line
A bar graph IS a chart.A bar graph IS a chart.A bar graph IS a chart.A bar graph IS a chart.
a double line graph is a graph that is same as a line graph but there are two lines
a bar graph is just a graph but a double bar graph compares 2 things!
A graph does not cook your meals when you are hungry! A graph does not show causation.
For comparison purposes, a multiple line graph would be best.
For comparison purposes, a multiple line graph would be best.
To compare data from different sources.
It makes it easier to work out values for x and y for graph plotting purposes.
A production possibilities frontier, or PPF, is a curve graph which shows combinations of two or more goods or services. The graph shows these goods or services being produced while using a maximum amount of resources.
the five graph is line graph,bar graph,pictograph,pie graph and coin graph
bar graph, double bar graph, line graph, and picto graph
72 degrees

If all the vertices and edges of a graph A are in graph B then graph A is a sub graph of B.
