## What is meant by line graph?

A **line graph** (also known as a **line plot** or **line chart**) is a **graph** which uses **lines** to connect individual data points that display quantitative values over a specified time interval. Used across many fields, this type of **graph** can be quite helpful in depicting the changes in values over time.

## What is a line graph used for?

**Line graphs** are **used to** track changes over short and long periods of time. When smaller changes exist, **line graphs** are better to **use** than bar **graphs**. **Line graphs** can also be **used to** compare changes over the same period of time for more than one group.

## What is a line graph look like?

The **line graph** consists of a horizontal x-axis and a vertical y-axis. Each axis is labeled with a data type. For example, the x-axis could be days, weeks, quarters, or years, while the y-axis shows revenue in dollars. Data points are plotted and connected by a **line** in a “dot-to-dot” fashion.

## What does a line graph tell us?

A **line graph** is commonly used to display change over time as a series of data points connected by straight **line** segments on two axes. **Line graphs** are useful in that they **show** data variables and trends very clearly and can help to make predictions about the results of data not yet recorded.

## What are the five parts of a line graph?

**The following pages describe the different parts of a line graph.**

- The Title. The title offers a short explanation of what is in your
**graph**. - The Legend. The legend tells what each
**line**represents. - The Source. The source explains where you found the information that is in your
**graph**. - Y-Axis.
- The Data.
- X-Axis.

## What are the types of line graph?

There are 3 main **types of line graphs** in statistics namely, a simple **line graph**, multiple **line graph**, and a compound **line graph**. Each of these **graph types** has **different** uses depending on the **kind** of data that is being evaluated.

## When should you use a line chart?

**When to use line charts**

**Use line charts**only if**you**want**to**show how values develop over time.**Line charts**work**to**show how different categories stand**to**each other (e.g.**to**show that**one**category overtook another**one**).**Line charts**work really well for a high number of values or values with different time intervals.

## What is the line on a graph called?

Glossary and Terms: **Graphs** and **Lines**. Abscissa – The horizontal **line**, or x-axis, of a **graph**. Axis – One of the **lines** that is used to form a **graph**. There is the horizontal x-axis and the vertical y-axis in a two dimensional **graph**.

## How do you read a line graph?

To **read** the **graph**, we look at the x axis to find one part of what we are looking for. We then draw an imaginary **line** straight up. We look for the actual **line** to see where it crosses our imaginary **line**.

## Is a zigzag line a function?

The zig-**function** is a periodic kink **function**

The points of the graph in which the slope changes from 1 to -1 or from -1 to 1 are called the kink points. In the case of zig, the kink points are (0, 1) en (2, -1).

## How do you plot a line on a graph?

To **plot** a point, just click on the **graph** with your left mouse button. To draw a **line**, hold down the left mouse button at one point on the **line** and drag the pointer to another point on the **line**. When you let go of the button the **line** will appear and it will automatically cross the whole **graph**.

## How do you plot a line?

The first step is to make sure that the equation of the **line** is in the Slope-Intercept Form, that is y = m x + b y=mx+b y=mx+b. Start by **plotting** the y-intercept which is (0,b). Find another point using the slope m with the y-intercept at the reference point. Connect the two points with a ruler.

## How does a line graph work?

**How does a line graph work**?

- First, we measure the value of something we want to keep track of at different points in time.
- Once we have lots of these measurements, we plot those points on our
**graph**, and then draw a**line**that connects those points, to make it easier to see how those values rose, fell, or stayed the same over time.

## What must a line graph have?

A **line graph has** two axes. The x-axis of a **line graph** shows the occurrences and the categories being compared over time and the y-axis represents the scale, which is a set of numbers that represents the data and is organized into equal intervals. It is important to know that all **line graphs must have** a title.
