Why Use Excel for Scatter Plots?

Before diving into the steps, it helps to understand why Excel is still a popular choice for scatter plot creation:

That said, Excel has limitations for advanced visualizations. For complex multi-panel figures or journal-specific formatting, tools like ConceptViz's scatter plot maker or dedicated software may be more efficient. We will discuss these alternatives later in the guide.

Step 1: Prepare Your Data

Proper data preparation is the foundation of a good scatter plot. Excel expects your data in a specific layout.

Data Layout Rules

• Column A (X-axis): Place the independent variable in the left column
• Column B (Y-axis): Place the dependent variable in the right column
• Headers: Include column headers in Row 1 (Excel uses these as axis labels)
• No blank rows: Remove any empty rows within your data range
• Numeric values only: Both columns must contain numbers, not text

Example Dataset

Here is a sample dataset showing the relationship between study hours and exam scores:

Tip: If your independent and dependent variables are not in adjacent columns, you can hold Ctrl (Windows) or Cmd (Mac) to select non-contiguous columns before inserting the chart.

---

Step 2: Select Your Data

1. Click on the first cell of your data range (including the header), for example cell A1
2. Drag to select all data through the last row and both columns
3. Make sure you include the header row — Excel uses it for chart labels

If your data has multiple series (e.g., Treatment A and Treatment B), select all columns together. We will cover multiple series in detail later.

---

Step 3: Insert the Scatter Chart

With your data selected:

1. Go to the Insert tab in the Excel ribbon
2. In the Charts group, click the Scatter (X, Y) chart icon
3. Select Scatter with only Markers (the first option) for a basic scatter plot

Excel will instantly generate a scatter chart embedded in your worksheet. The X-axis will display values from your left column, and the Y-axis will show values from your right column.

Scatter Chart Subtypes in Excel

Excel offers several scatter chart variations:

For most research and analysis purposes, Scatter with only Markers is the correct choice. The other options can visually imply connections between data points that may not exist.

Step 4: Add a Chart Title

Excel may insert a generic title like "Chart Title" or use your column header. To customize it:

1. Click on the chart title text
2. Delete the default text
3. Type a descriptive title, such as "Study Hours vs. Exam Score"

Chart Title Best Practices

• Be specific: "Effect of Study Hours on Exam Performance" is better than "Scatter Plot"
• Include variables: Mention both the X and Y variables
• Add units if relevant: "Temperature (°C) vs. Reaction Rate (mol/s)"
• Keep it concise: One line is ideal; two lines maximum

For academic papers, follow the convention of your target journal. Many journals require figure captions below the chart rather than a title above it, as explained in our guide on how to make figures for Nature and Science journals.

---

Step 5: Add and Format Axis Titles

Axis titles are critical for scatter plots. Without them, readers cannot interpret your chart.

Adding Axis Titles

1. Click on the chart to select it
2. Click the + (Chart Elements) button that appears at the top-right corner of the chart
3. Check the Axis Titles box
4. Click on each axis title to edit the text

Formatting Tips

• X-axis title: Name the independent variable with units — e.g., "Temperature (°C)"
• Y-axis title: Name the dependent variable with units — e.g., "Growth Rate (cm/day)"
• Font size: Use 10--12 pt for axis titles, matching your document font
• Rotate Y-axis title: Excel automatically rotates it; ensure it is readable

Step 6: Add a Trend Line

A trend line (or line of best fit) reveals the overall direction of your data. This is one of the most valuable features of Excel scatter plots.

How to Add a Trend Line

1. Click on any data point in your scatter plot (this selects the entire series)
2. Right-click and choose Add Trendline, or click the + button and check Trendline
3. In the Trendline Options pane, select the regression type

Trend Line Types

Display the Equation and R-squared Value

To show the regression equation and goodness-of-fit:

1. Double-click the trend line to open the Format Trendline pane
2. Scroll to the bottom of the Trendline Options
3. Check Display Equation on chart
4. Check Display R-squared value on chart

The R-squared value (R^2) indicates how well the trend line fits your data:

• R^2 > 0.9: Strong fit — the trend line explains most of the variation
• R^2 = 0.5 to 0.9: Moderate fit — some relationship exists
• R^2 < 0.5: Weak fit — the variables may not be linearly related

A scatter plot with regression trend line — adding R-squared values helps quantify the strength of the relationship

Step 7: Format the Axes

Default axis formatting in Excel is often not ideal. Here is how to improve it.

Adjust Axis Scale

1. Double-click on an axis to open the Format Axis pane
2. Under Axis Options, set custom minimum and maximum values
3. Adjust the major and minor tick mark intervals

Why adjust the scale? By default, Excel may add excessive white space around your data. Tightening the axis bounds to match your data range makes patterns easier to see.

Format Axis Numbers

• Right-click the axis labels and select Format Axis
• Under Number, choose the appropriate format (e.g., number with 1 decimal place)
• For large values, consider scientific notation

Add Gridlines (Optional)

Gridlines help readers estimate values but can clutter a chart. To toggle them:

1. Click the + button on the chart
2. Check or uncheck Gridlines
3. Choose Major, Minor, or both

For clean, professional charts, use light gray major gridlines only or remove gridlines entirely.

Step 8: Customize Data Point Appearance

Formatting your data markers improves readability, especially when presenting to audiences.

Change Marker Style

1. Click on a data point to select the series
2. Right-click and select Format Data Series
3. Under Marker Options, choose the marker type, size, and color

Recommended Settings for Research

Adding transparency is especially useful when many points overlap. This technique reveals data density without needing to change to a different chart type.

Working with Multiple Data Series

Research often requires comparing two or more groups on the same scatter plot — for example, treatment vs. control, or male vs. female participants.

Method 1: Data in Adjacent Columns

If your data is organized with a shared X column and multiple Y columns:

1. Select all three columns (including headers)
2. Insert a Scatter chart
3. Excel automatically creates two series with different colors

Method 2: Add Series Manually

If your groups have different X values:

1. Create the scatter plot with the first group
2. Right-click the chart and select Select Data
3. Click Add under Legend Entries (Series)
4. Set the Series X values and Series Y values to your second group's data
5. Click OK

Differentiating Multiple Series

Use distinct visual attributes for each series:

• Different colors: Blue for Group A, red for Group B
• Different marker shapes: Circles vs. triangles vs. squares
• Add a legend: Click + > Legend to show which series is which
• Separate trend lines: Right-click each series individually to add its own trend line

A multi-group scatter plot — using different colors and markers makes it easy to compare groups

Adding Data Labels to Scatter Points

Data labels identify individual points, which is useful when you have a small number of observations or need to highlight specific values.

Basic Data Labels

1. Click on the data series in the chart
2. Click the + button and check Data Labels
3. Choose a position: Above, Below, Left, Right, or Center

Custom Labels from Cell Values

By default, Excel labels points with Y values. To use custom text (e.g., sample names):

1. Click on the data labels to select them
2. Right-click and choose Format Data Labels
3. Under Label Contains, check Value From Cells
4. Select the cell range containing your label text
5. Uncheck Y Value to show only your custom labels

Pro tip: For scatter plots with many points, label only outliers or key observations to avoid clutter. You can delete individual labels by clicking once on all labels (to select the series) and then clicking again on the specific label you want to remove.

Common Scatter Plot Mistakes in Excel

Avoid these frequent errors when creating scatter plots:

1. Using a Line Chart Instead of a Scatter Chart

Line charts and scatter charts look similar but behave differently. Line charts space categories evenly on the X-axis regardless of their actual values. Scatter charts plot points at their true X-Y coordinates.

Always use Insert > Scatter for two continuous numerical variables.

2. Swapped Axes

If your chart looks wrong, you may have the X and Y variables reversed. To fix this:

1. Right-click the chart and select Select Data
2. Click Edit on the series
3. Swap the Series X values and Series Y values

3. Including Non-Numeric Data

Scatter charts require both axes to be numerical. If you have text or dates mixed with numbers, Excel may plot them incorrectly or produce an error.

4. Overcrowded Charts

If you have hundreds or thousands of points, individual markers will overlap heavily. Solutions include:

• Reduce marker size
• Add transparency
• Use a 2D density plot instead (not available natively in Excel)
• Consider a dedicated tool like ConceptViz scatter plot maker which handles large datasets with automatic density visualization

5. Missing Axis Labels

A scatter plot without axis labels is meaningless. Always label both axes with variable names and units.

6. Inappropriate Trend Line

Do not add a linear trend line to clearly non-linear data. Always visually inspect the scatter plot first, then choose the regression type that best fits the pattern.

Excel Scatter Plot Shortcuts and Time-Savers

These tips will speed up your scatter plot workflow:

Saving a Chart Template

If you create scatter plots frequently (e.g., for a thesis with 20+ figures), saving a template ensures consistency:

1. Format one chart exactly how you want it
2. Right-click the chart and select Save as Template
3. Name the template (e.g., "thesis-scatter")
4. For future charts, go to Insert > Charts > All Charts > Templates

---

Scatter Plots for Academic and Research Use

If you are preparing scatter plots for a research paper, thesis, or conference poster, extra formatting steps are necessary.

Journal Requirements Checklist

• Resolution: 300 DPI minimum (use "Save as Picture" with high-quality settings)
• Font: Match the journal's required typeface (often Arial or Helvetica)
• Font size: Axis labels 8--10 pt, titles 10--12 pt when printed at final size
• Colors: Use colorblind-friendly palettes (avoid red-green combinations)
• File format: TIFF or EPS for most journals; PNG for online submissions
• Figure caption: Add a descriptive caption below the chart (not in the chart title)

For detailed guidance, see our comprehensive guide on creating figures for Nature and Science journals.

Exporting from Excel

To save a high-quality scatter plot image from Excel:

1. Click on the chart to select it
2. Right-click and choose Save as Picture
3. Select PNG or TIFF format
4. For higher resolution, copy the chart and paste it into PowerPoint, then export at 300 DPI

Important limitation: Excel's default image export resolution is 96 DPI, which is too low for journal publication. The PowerPoint method or using a vector format (EMF) produces better results.

Experimental data plotted as a scatter chart — this format is standard in scientific papers across disciplines

Excel vs. Dedicated Scatter Plot Tools

While Excel is convenient, it is worth considering when a dedicated tool might serve you better.

When to Stay with Excel

• Quick exploratory analysis during data collection
• Simple scatter plots with fewer than 500 data points
• Charts for internal reports or presentations
• When your team only uses Microsoft Office

When to Switch Tools

• Publication-quality figures with strict formatting requirements
• Datasets with thousands of data points
• Multi-panel figures combining several scatter plots
• Reproducible workflows where you need to regenerate charts from updated data

Advanced: Scatter Plot with Error Bars

Error bars communicate uncertainty in your data, which is essential for scientific scatter plots.

Adding Error Bars

1. Click on the data series in the chart
2. Click the + button and check Error Bars
3. Click the arrow next to Error Bars and select More Options
4. Choose the error amount: Fixed value, Percentage, Standard deviation, or Custom

Custom Error Bars from Data

For research, you typically calculate error values separately (e.g., standard error of the mean):

1. In the Format Error Bars pane, select Custom
2. Click Specify Value
3. Set the Positive Error Value to your upper error range cells
4. Set the Negative Error Value to your lower error range cells

Error bars can be added independently to both X and Y directions, which is common in physics and engineering scatter plots.

---

Advanced: Creating Quadrant Charts

A quadrant chart divides a scatter plot into four regions, useful for portfolio analysis, performance reviews, or risk assessment.

How to Create Quadrants

1. Create a standard scatter plot
2. Add vertical and horizontal reference lines at your threshold values
3. To add reference lines, use the Error Bars trick:
   • Add a single data point at the intersection of your threshold values
   • Add error bars extending to the axis limits
   • Format the error bars as dashed lines

Alternatively, add two separate data series: one horizontal line and one vertical line, each with two points defining the line endpoints.
