## Line Graph

Line Graph – Infinity Learn;

- A line graph is a graphical representation of data, in which points are plotted on a coordinate plane, with the abscissa representing the independent variable and the ordinate representing the dependent variable. The points are connected by lines, which can be straight or curved.
- Line graphs are often used to display data over time, and they can be used to show how one variable changes as another changes. They can also be used to compare two or more sets of data.
- There are a few things to keep in mind when reading or interpreting line graphs. First, it is important to note the scale on the axes, as the points on the graph may not be evenly spaced. Second, it is important to understand how the data is being measured. For example, if one variable is increasing or decreasing at a constant rate, the line on the graph will be a straight line. If the rate of change is not constant, the line on the graph will be curved. Finally, it is important to pay attention to the trend of the data. For example, if the data is trending upwards or downwards, the line on the graph will be trending in the same direction.

## How to Make a Line Graph

There are a few simple steps to follow in order to make a line graph.

- Step 1: Choose the data you want to graph.
- Step 2: Convert the data into numbers that can be graphed.
- Step 3: Plot the points on a graph.
- Step 4: Draw a line through the points.

## What is a Line Graph?

A line graph is a graphical representation of data in which points are plotted on a coordinate plane using line segments to connect them. The points are usually connected in order of increasing or decreasing values. The line graph allows for the visualization of trends in the data.

## Line Graph Definition

A line graph is a graph that shows the change in a variable over time. The variable is typically shown on the vertical axis, and time is shown on the horizontal axis. A line graph will show a line connecting the points where the value of the variable was measured.

## Parts of Line Graph

- A line graph consists of points plotted in two dimensions, typically Cartesian coordinate axes.
- The data plotted is usually time-series data, meaning that it is measured at successive points in time.
- The points are connected by a line, which represents the trend of the data.
- The line graph can show the trend of a single data series or of multiple data series.

## Types of Line Graphs

There are four types of line graphs:

1. Continuous Line Graph

2. Step Line Graph

3. Pie Chart

4. Bar Graph
