Type of Graphs and Charts

What is graph

A Graph is a type of Chart which is used to show the mathematical relationship between varied sets of data by plotting on it’s Horizontal (X-axis) and Vertical (Y-axis). Graphs can be used for raw data as well and provide a visual representation of trends and changes in the data over a period of time. Graphs find their usage more in Analysis using both raw data and exact numbers and as such shows, accurate numerical figures plotted on its axes.

What is chart

A Chart represents information that can be in the form of diagram, table or graph itself and it comprises various methods for presenting large information. Ideal for those forms of data which can be easily structured or Categorized into small subsets of simple and easily understandable figures. Charts find their excess use in business presentations and in showing survey results. Example Pie Charts are the most popular ones used in Business Presentations.

Type of Graphs and Charts

There are several different types of graphs and charts, their uses and names, Here we discussed popular chart and graph with examples and pictures.

Line graph

Line graphs illustrate how related data changes over a specific period of time. One axis might display a value, while the other axis shows the timeline. Line graphs are useful for illustrating trends such as temperature changes during certain dates.

Bar graph

Bar graphs offer a simple way to compare numeric values of any kind, including inventories, group sizes and financial predictions. Bar graphs can be either horizontal or vertical. One axis represents the categories, while the other represents the value of each category. The height or length of each bar relates directly to its value.

Histogram

A histogram shows continuous data in ordered rectangular columns. Usually, there are no gaps between the columns.The histogram displays a frequency distribution (shape) of a data set. At first glance, histograms look alike to bar graphs. However, there is a key difference between them. Bar Chart represents categorical data and histogram represent continuous data.

Pictograph

A pictograph uses pictures or symbols to display data instead of bars. Each picture represents a certain number of items. Pictographs can be useful when you want to display data in a highly visual presentation such as an infographic. For example, you could use a picture of a book to display how many books a store sold over a period of a few months.

Pictograph

Area graph

Area graphs show a change in one or more quantities over a certain period of time. They often help when displaying trends and patterns. Similar to a line graph, area graphs use dots connected by a line. However, an area graph involves coloring between the line and the horizontal axis. You can use several lines and colors between each one to show how multiple quantities add up to a whole. For example, a retailer might use this method to display the profits of different stores over the same timeframe.

Scatter plot

Scatter plots use dots to depict the relationship between two different variables. Someone might use a scatter plot graph to show the relationship between a person’s height and weight, for example. The process involves plotting one variable along the horizontal axis and the other variable along the vertical axis. The resulting scatter plot demonstrates how much one variable affects the other. If there is no correlation, the dots appear in random places on the graph. If there is a strong correlation, the dots are close together and form a line through the graph.

Scatter plot

Pie chart

A pie chart presents the different parts of a whole. It looks like a circle divided into many pieces, much like a pie cut into slices. The pieces are different sizes based on how much of the whole they represent. Each piece usually has a label to represent its value compared to the whole. Professionals can use pie charts in business presentations to demonstrate population segments, market research responses and budget allocations.

Gauge chart

Gauge charts display data as a reading on a dial. They show where a specific data point is within a minimum or maximum range. A needle depicts the value within a scale. Many people use gauge charts to illustrate speed, revenue goals and temperatures.

Stacked Bar Chart

Stacked Bar Chart should be used to compare many different items and show the composition of each item being compared.

Bubble Chart

A bubble chart is similar to a scatter plot in that it can show distribution or relationship. There is a third data set, which is indicated by the size of the bubble or circle.
