# Excel Tutorial: How To Make A Line Graph In Excel With 3 Variables

## Introduction

Line graphs in Excel are a powerful tool for visualizing trends and patterns in data. When working with three variables, creating a line graph can help you easily compare and analyze the relationships between them. In this tutorial, we will walk through the step-by-step process of creating a line graph in Excel with three variables, so you can effectively present and interpret your data.

## Key Takeaways

• Line graphs in Excel are a powerful tool for visualizing trends and patterns in data.
• Creating a line graph with three variables allows for easy comparison and analysis of their relationships.
• Proper organization and setup of the Excel sheet is essential for creating an effective line graph.
• Customizing the graph with axis labels, title, and line styles helps in accurately presenting the data.
• Interpreting the trends and patterns in the graph and providing context and analysis is crucial for deriving insights and conclusions.

## Understanding the data

A. Explain the three variables that will be used in the line graph

When creating a line graph in Excel with 3 variables, it is important to understand the three variables that will be used. These could be, for example, time, temperature, and humidity. Each variable will be plotted on the graph to show their relationship over time.

B. Provide an overview of the data set that will be used for the tutorial

For this tutorial, we will use a sample data set that includes time as the independent variable and temperature and humidity as the dependent variables. The data set will include multiple data points for each variable, allowing us to create a comprehensive line graph with 3 variables in Excel.

## Setting up the Excel sheet

Before creating a line graph with three variables in Excel, it is important to set up the Excel sheet properly to ensure the data is organized and ready for graphing.

A. Open a new Excel document
• Launch Microsoft Excel on your computer.
• Open a new Excel document or use an existing one where you want to create the line graph.

B. Input the three variables into separate columns
• Once the Excel sheet is open, input the three variables into separate columns. For example, if you are plotting sales, expenses, and profit over time, you would input the dates in one column and the corresponding sales, expenses, and profit data in separate columns.
• Ensure that the data is entered accurately to avoid any errors in the graphing process.

C. Ensure the data is organized properly for graphing
• Make sure that the data is organized properly for graphing. This may include sorting the data by date or any other relevant factor to ensure the graph is displayed correctly.
• Double-check the data to ensure there are no missing values or inconsistencies.

## Creating the line graph

When working with three variables in Excel, it's important to create a line graph that effectively visualizes the data. Follow these steps to create a line graph with three variables:

A. Select the data to be included in the graph

Before creating the line graph, ensure that the data for the three variables is organized and ready for visualization. Select the range of cells that contain the data for all three variables.

B. Navigate to the "Insert" tab and select "Line Graph"

Once the data is selected, navigate to the "Insert" tab in the Excel ribbon. Then, select the "Line Graph" option from the chart options available. This will open a dropdown menu with various line graph styles to choose from.

C. Choose the appropriate line graph style for the three variables

After selecting the "Line Graph" option, choose the appropriate line graph style that best suits the visualization of the three variables. Consider options such as the 3D line graph or the stacked line graph to effectively display the relationship between the variables.

## Customizing the graph

Once you have created a line graph with 3 variables in Excel, you can further customize it to make it more visually appealing and easier to interpret. Here are a few ways to customize your graph:

• Adjust the axis labels to accurately represent the variables
• When working with 3 variables in a line graph, it's important to ensure that the x and y-axis labels accurately represent the data being plotted. You can customize the axis labels by right-clicking on the axis, selecting "Format Axis," and then adjusting the labels in the "Axis Options" menu.

• Add a title to the graph
• Adding a title to your graph can help viewers understand the context of the data being presented. To add a title, simply click on the "Chart Title" placeholder and enter the desired title for your graph.

• Customize the color and style of the lines for each variable
• To differentiate between the 3 variables in your line graph, you can customize the color and style of the lines. By right-clicking on a data series, selecting "Format Data Series," and then choosing the desired line color and style, you can make each variable stand out on the graph.

After creating a line graph in Excel with 3 variables, it’s important to analyze the trends and patterns shown in the graph, provide additional context or information related to the data, and offer insights or conclusions based on the graph.

A. Interpret the trends and patterns shown in the graph
• ### Identify the relationships

Look for any upward or downward trends for each variable and how they interact with each other. For example, are there any correlations or patterns that can be observed between the variables?

• ### Highlight significant points

Identify any peaks, valleys, or other significant points on the graph. These points can provide valuable insight into the data and help in understanding the overall trend.

B. Provide additional context or information related to the data
• ### Source of data

It’s important to mention where the data comes from and any pertinent information about its collection. This can help in better understanding the context of the graph.

• ### External factors

Consider any external factors that may have influenced the data. This could include economic conditions, market trends, or other variables that may have impacted the results shown in the graph.

C. Offer insights or conclusions based on the graph
• ### Identify key takeaways

Determine the key insights that can be drawn from the graph. This could include identifying areas of growth, decline, or stability within the data.

• ### Implications for decision making

Discuss how the information gleaned from the graph can be used to make informed decisions. This could include potential strategies for improvement, areas for further analysis, or potential risks to be aware of.

## Conclusion

Creating a line graph in Excel with three variables is a powerful way to visualize data and showcase trends. To summarize, the steps include entering the data into the spreadsheet, selecting the data range, and choosing the line graph option from the Insert tab. It's important to ensure that the data is accurately represented and labeled for clarity.

Effectively visualizing data is crucial for understanding trends and patterns, making informed decisions, and communicating information clearly to others. Line graphs are a valuable tool for displaying the relationships between three variables over time or categories.

We encourage you to continue exploring and experimenting with Excel's graphing capabilities to unlock the full potential of your data visualization skills. Whether it's adding additional variables or customizing the appearance of your graphs, Excel offers a wide range of options to create impactful visual representations of your data. Keep exploring, and the possibilities are endless!
