If the data does not change continuously, it is called discrete data, and is commonly compared by use of a bar chart.
Technical note: please note the use of the word chart, graph is commonly misused in a mathematical sense like this. A graph, mathematically, is a series/group of nodes that represent information and are connected by lines/edges that represent a link to other information. Bar graphs, line graphs, histogram graphs, bubble graphs, area graphs etc, are all technically chartsnot graphs. For more info see the link below on graph theory.
Bar graph :)
it can show data easy to compare
Any graph can be used for such a purpose.
A double bar graph is a graph that uses pairs of bars to compare and show the relationship between data. However, a double line graph is a grid graph that uses pairs of lines to compare and show the relationship between data.
to represent and compare datas to it.
Bar.?
A Bar Graph
Bar graph :)
yes
A dot plot
it can show data easy to compare
frequency table
You can retrieve information quickly, unlike a graph. It is also easier to compare, and to find the rate of change.

Pie or sector graph
to represent and compare datas to it.
