## What does a double line graph show?

A double line graph is a line graph with two lines connecting points to show a continuous change. The x-axis of a double line graph shows the occurrences and the categories being compared over time, and the y-axis represents the scale.

**What are double line graphs best for?**

Double-line graphs show how two sets of related data change over a period of time.

**Can you use a line graph for temperature?**

A line graph is also used when there are two variablesâ€”but only makes sense when you’re tracking changes over a continuous measurement (e.g., time, temperature, distance). Line graphs are especially useful for illustrating direction (i.e., peaks and dips) rather than magnitude.

### Where does temperature go on a line graph?

You may be told which axis to use for which variable.) If you are told to make a graph of “temperature vs. time”, that means temperature is on the y-axis and time is on the x-axis.

**Which graph is used for temperature?**

line graph

Temperature is shown on a line graph, with the figures being shown on the right side of the graph. Rainfall is shown by a bar graph, with the figures being shown down the left side of the graph.

**How do you read a line graph?**

The horizontal scale across the bottom and the vertical scale along the side tell us how much or how many. The points or dots on the graph represents the x,y coordinates or ordered pairs. The line segments connecting the points give estimated values between th points.

#### When would you use a double bar graph?

A double bar graph is used to display two sets of data on the same graph. For example, if you wanted to show the number of hours that students worked in one month compared to another month, we would use a double bar graph.

**When do you use a double line graph?**

In this lesson, we defined a double line graph as a line graph with two lines that connect points to show a continuous change, and we explored the features, functions, and examples of a double line graph. We learned that we can use a double line graph when comparing two sets of data.

**Which is an example of a line graph?**

In Example1, the temperature changed from day to day. In Example 2, the value of Sarah’s car decreased from year to year. In Example 3, Sam’s weight increased each month. Each of these graphs shows a change in data over time. A line graph is useful for displaying data or information that changes continuously over time.

## What do the labels mean on a line graph?

Let’s define the various parts of a line chart. The title of the graph tells us what the graph is about. The horizontal label across the bottom and the vertical label along the side tells us what kinds of facts are listed.

**What do the dots on a line graph mean?**

The horizontal scale across the bottom and the vertical scale along the side tell us how much or how many. The points or dots on the graph show us the facts. The lines connecting the points give estimates of the values between the points.
