A list of the different types of graphs and charts and their uses with examples and pictures. Types of charts in statistics, in economics, in science.
Different types of graphs and charts are needed to present results from experiments. Graphs and charts need to be drawn and labelled correctly.
- Finite Graphs. A graph is said to be finite if it has a finite number of vertices and a finite number of edges. A finite graph is a graph with a finite number of vertices and edges.
- Infinite Graph: A graph is said to be infinite if it has an infinite number of vertices as well as an infinite number of edges.
- Trivial Graph: A graph is said to be trivial if a finite graph contains only one vertex and no edge. A trivial graph is a graph with only one vertex and no edges.
- Simple Graph: A simple graph is a graph that does not contain more than one edge between the pair of vertices. A simple railway track connecting different cities is an example of a simple graph.

- Summary
In science, we often utilise graphs due to their ability to help simplify and visualise complex data sets which make it easier for us to interpret and analyse data. In doing this, they can help us to observe any patterns or trends which might otherwise not have been immediately apparent in the raw data. There are four types of graphs which you will...
A column graph is a vertical bar graph which displays data using rectangular bars. The height of the bar of the column graph (y-axis) represents magnitude. Each of the individual bars (x-axis) corresponds to a category. As such, column graphs are ideal for comparing different categories or groups and are used generally when there are a larger numbe...
A histogram is a column-graph-like chart which uses rectangular bars called "bins" to display data. The height of each bar on the column graph (y-axis) represents population size, while each of the "bins" (x-axis) represents either a range or a discrete value. Histograms are utilised to help identify broader patterns in the distribution of data. An...
Scatter plots present data as individual points n a graph. The scatter plot is used ideally when both the x and the y-axis consists of numerical data. They are used to help identify correlations between two continuous numerical variables where the x-axis represents the independent variables, and the y-axis represents the dependent variable. Scatter...
A line graph is a type of graph which displays data as a series of data points connected by straight line segments. For line graphs, the x-axis typically represents time while the y-axis can represent any other secondary variable. Thus, they are usually used to identify trends in variables over time.
Selecting the right graph depends heavily on the data you are working with and what you want to highlight. It's important to familiarise yourself with different types of graphs and understand when to use each for effective communication of your scientific findings.
3 days ago · Because graphs are so pervasive, it is useful to define different types of graphs. The following are the most common types of graphs: Undirected graph: An undirected graph is one in which its edges have no orientations, i.e. no direction is associated with any edge.
Learn how to read and interpret graphs and other types of visual data. Uses examples from scientific research to explain how to identify trends.
Aug 22, 2021 · Graphs and charts communicate information visually. They can show patterns, help scientists identify correlations, and get the point of the experiment across quickly. Typically, the independent variable is plotted on the x-axis. The dependent variable is plotted on the y-axis.
