Understanding Different Types of Graphs: Features and Functions Explained
This guide explores various types of graphs, including tables, bar graphs, line graphs, pie charts, flow charts, and maps. Each type is analyzed based on its capacity, suitability for different data types, and unique features. For instance, tables can accommodate large datasets, pie charts illustrate proportions, while bar and line graphs effectively highlight patterns and trends in both nominal and numerical data. Flow charts detail processes sequentially, and maps illustrate locations and directions. Gain insights into the optimal use of each graph type for data presentation.

Introducing graphs Table Bar graph Line graph Pie chart Flow chart Maps
Features of Each Type of Graph Table large capacity (eg. 50 rows on a A4), patterns not easily identified suits nominal as well as numerical data able to show cross-sectional & longitudinal data Pie chart: limited capacity nominal & numerical data (%) suits cross-sectional data unless used in series 30 items/variables
Bar graph /Line graph: Similarities: large capacity; suit cross-sectional & longitudinal data; easy to identify patterns and trends Differences: bar graphs better for discrete data; line graphs more for continuous data
Flow chart: for processes /procedures, usually sequential Maps: multi-directional; locations & directions Language features: Flow chart: conjunctions describing sequence Maps: words showing locations and directions Some vocabulary (eg. ordinal) applies to most other graphs, eg. rank first, account for, a significant increase/decrease Some vocabulary only for line graphs, eg. fluctuation, steady rise, plummet, soar
