## What are line graphs mainly used for?

Line graphs are used to track changes over different periods of time. Line graphs can also be used as a tool for comparison: to compare changes over the same period of time for more than one group.

## What type of data is line graph used for?

Line graphs, also called line charts, are used to represent quantitative data collected over a specific subject and a specific time interval. All the data points are connected by a line. Data points represent the observations that are collected on a survey or research.

What are double line graphs used for?

A double line graph is used to compare the changes or the growth in two trends over a period of time. It is preferred to use double line graphs in case of continuous data. For example, if you want to compare the changes in the growth in sales of two companies from the year 2000 to 2020, you can use double line graphs.

### What is the meaning of line graph?

Definition of line graph : a graph in which points representing values of a variable for suitable values of an independent variable are connected by a broken line.

### What is line graph in statistics?

A line graph shows the changes over time for a continuous variable. A line graph may also be called a line chart, a trend plot, run chart or a time series plot.

Can you use a line graph for discrete data?

Examples. Discrete data is best represented using bar charts. Temperature graphs would usually be line graphs because the data is continuous . When you are graphing percentages of a distribution a pie chart would be suitable.

#### What are the two types of line graph?

The following are the types of the line graph. They are: Simple Line Graph: Only one line is plotted on the graph. Multiple Line Graph: More than one line is plotted on the same set of axes.

#### What is line graph example?

A line graph, also known as a line chart, is a type of chart used to visualize the value of something over time. For example, a finance department may plot the change in the amount of cash the company has on hand over time. The line graph consists of a horizontal x-axis and a vertical y-axis.

What is a line graph presentation?

A line graph is used to show a trend, usually over time. There can be a single data series to show one trend or multiple data series to show trends that can be compared to each other.

## What graphs are used for continuous data?

Continuous data are measured on a scale or continuum (such as weight or test scores). Histograms are useful for displaying continuous data. Bar graphs, line graphs, and histograms have an x- and y-axis. The x-axis is the horizontal part of the graph and the y-axis is the vertical part.
