You can use different type of graphs to show a data.
Examples: Bar graphs, double bar graphs, circle graphs, line graphs and pictographs
Advantage: It can be easily 2-3 data sets and it's visually strong.
Bar Graphs: Best for comparing across categories. It is a graph where the length of a bar represents a certain amount.
Disadvantage: Graph categories can be reordered to emphasize certain effects and can use only with discrete data.
Double Bar Graphs: Best for comparing two sets of data across categories. It is chart with rectangular bars with lengths proportional to the values that they represent.
Advantage: Beautiful and neatly constructed diagrams/charts are more attractive then
Disadvantages: Can be tempting to compare too many things, graph becomes convoluted
and difficult to understand. Limited space for labelling with vertical bar graphs
Circle Graph: Best for comparing categories to the whole using percents. It used to compare parts and show their relationship to a whole. These work well for showing percentages and fractions.
Advantage: Visually appealing, Shows percent of total for each category
Disadvantage: No exact numerical data and it is hard to compare 2 data sets.
Line Graph: Best for showing changes over time.. It is a graph that uses line segments to show changes in data; the data usually represents a quantity changing over time.
Advantage: Can compare multiple continuous data sets easily
Disadvantage: Use only with continuous data
Pictograph: Best for comparing data that can be easily counted and represented using symbols. It is a graphic character used in picture writing.
Advantages: Easy to read, Visually appealing
Disadvantages: Hard to quantify partial icons, Icons must be of consistent size
