How to Create a Scatter Plot In Excel: Step by Step Guide

A scatter plot in Excel is a powerful visualization tool for identifying trends, relationships, and patterns between two variables. By plotting data points on an Excel XY scatter plot, you can gain insights into correlations and outliers, making it an essential tool for data analysis. Whether you’re comparing sales and expenses, analyzing scientific data, or forecasting trends, scatter plots provide a clear picture of how two datasets interact. In this guide, we’ll walk you through the steps to create a scatter chart in Excel, including tips for switching axes and applying advanced techniques to refine your visuals.

Disclaimer: Always ensure your data is accurate and well-organized to produce reliable and insightful visualizations.

How to Make a Scatter Plot in Excel

Learning how to build a scatter plot in Excel is simple and allows you to visually analyze relationships between data points. Follow these steps to create a scatter graph in Excel and customize your scatter chart:

Step 1: Prepare Your Data

Organize your data into two columns:

• One column for the X-axis values (independent variable).
• The second column for the Y-axis values (dependent variable).

Example:

Step 2: Select the Data

• Highlight both columns of data, including the headers.
• Ensure that the data is clean, with no blank cells or text in numerical ranges.

Step 3: Customize the Chart

• Go to the Insert tab on the Excel ribbon.
• In the Charts group, find the Insert Scatter (X, Y) Chart dropdown.
• Select one of the following Scatter Plot options:

Scatter Chart(standard, with just points)

Displays individual data points (dots) to show relationships or correlations between two variables.

Scatter Plot with Smooth Lines

Connects data points with smooth, curved lines to display the overall trend. It is Ideal for showing non-linear relationships or smooth transitions in data.

Scatter Plot with Straight Lines

Connects data points with straight lines to emphasize trends or links between points. It is Used when you want to clearly show data progression or paths.

Step 4: Customizing XY scatter plot

1: Add Chart Title

• Click on the default Chart Title at the top of the chart.
• Type a meaningful title, such as "Advertising Spend vs. Sales Revenue".

2: Add Axis Titles

• Click the chart to activate the Chart Elements button (the “+” icon).
• Check the Axis Titles box.

Rename the titles:

• Horizontal Axis: "Advertising Spend (USD)".
• Vertical Axis: "Sales Revenue (USD)".

3: Format the Data Points

Right-click on any data point (dot) and select Format Data Series.

Customize the data points:

• Change the color of the dots.
• Adjust the marker style (e.g., circles, squares, or triangles).
• Increase or decrease the marker size for visibility.

4: Add Data Labels (Optional)

To display values next to the data points:

• Right-click on a data point.
• Select Add Data Labels.
• Move or customize the labels for clarity.

5: Add a Trendline

If you want to visualize the overall trend in the data:

• Right-click on any data point.
• Select Add Trendline.

In the Format Trendline pane:

• Choose Linear for a straight line.
• Check Display Equation on chart to see the line equation.
• Check R-squared value to measure the correlation strength.

6: Adjust Axis Scale

• Right-click on the X-axis or Y-axis.
• Choose Format Axis.
• Adjust the Minimum and Maximum Bounds to focus on a specific range.

Step 5: Save and Update the Scatter Plot

• Save your Excel workbook to keep your chart.
• If you update the data in the table, the Scatter Plot will automatically refresh.

How to Switch X and Y Axes in a Scatter Plot

In an Excel XY scatter plot, Excel plots the independent variable on the horizontal (X-axis) and the dependent variable on the vertical (Y-axis). If you need to swap the X and Y axes, this scatter plot tutorial makes it easy with the following steps:

Step 1: Select the Scatter Chart

Click on the chart to activate it. Small handles will appear around the chart area.

Step 2: Open the "Select Data Source" Window

Right-click on the chart and choose "Select Data" from the context menu.

Step 3: Edit the Data Series

In the Select Data Source window, choose the series you want to swap and click Edit.

Step 4: Swap the X and Y Values

• In the Edit Series dialog box:
• For Series X values, select the range that was originally for the Y values.
• For Series Y values, select the range that was originally for the X values.
• Click OK to apply changes.

Step 5: Close and Refresh

• Click OK again to close the Select Data Source window.
• Your X and Y axes will now be swapped in the scatter chart.

Advanced Techniques for Scatter Plots

When working with a scatter chart in Excel, you can use advanced techniques to make your analysis more insightful and visually appealing.

1. Add Trendlines and Analyze R-Squared Values

• Add a Trendline: Insert a trendline to visualize the overall direction or pattern of data. In Excel, right-click on a data series and choose Add Trendline.
• R-Squared Value: Enable the R-squared value to measure how well the trendline fits the data. Higher values (close to 1) indicate a stronger correlation.
• Types of Trendlines: Choose between linear, polynomial, or exponential trendlines based on your dataset.

2. Combine Scatter Plots with Other Chart Types

• Overlay Line Charts: Combine scatter plots with line charts to show trends or averages alongside individual data points.
• Use Dual Axes: Add a secondary axis to compare variables with different scales.
• Layer with Bar Charts: Pair scatter plots with bar charts to provide context, such as categorical data alongside continuous variables.

These techniques enhance the depth of your scatter plot analysis and make your visualizations more impactful.
