# How to Create Bubble Chart in Excel with 3 Variables

Typical Excel Charts depict a two-dimensional (X and Y) representation of data. Working with three-dimensions (or 3 variables) requires the insertion of a bubble chart into Excel, where the third variable is the size of the bubbles. In this article, we’ll demonstrate the step-by-step procedure to create a bubble chart in Excel with 3 variables.

First, we will prepare our dataset. Then, we will insert a Bubble Chart. Finally, we will modify the Bubble Chart with 3 variables.

### Step 1 – Preparing a Dataset to Create a Bubble Chart

We’ll use the following dataset named Project Details containing 3 variables: Cost, Profit, and Profit Rate.

### Step 2 – Inserting a Bubble Chart

Excel offers 2 types of bubble charts: 2D Bubble and 3-D Bubble. We can use either to insert a bubble chart with 3 variables.

• Go to the Insert tab and click on Insert Scatter from the Charts group.
• Choose Bubble under Bubble.

### Step 3 – Modifying the Bubble Chart

After clicking on the Bubble in the Insert Scatter options, a bubble chart is inserted into the worksheet as displayed in the below picture. However, the inserted chart needs modifications.

#### Step 3.1 – Formatting the X-Axis

• Select the X-Axis and right-click on it.
• Click on Format Axis from the context menu.
• In the Axis Options, set Minimum and Maximum X-Axis Bounds as shown in the following image.

#### Step 3.2 – Displaying Data Labels from Cells

• Click on the Chart.

The Chart Elements (Plus Icon) pane appears.

• Tick chart elements such as Axes, Axis Titles, or Chart Title as desired.
• Click Data Labels > More Options.

The Format Data Labels dialog box appears.

• Tick Value From Cells.

The Data Label Range dialog box opens.

• Assign the range (Profit Rate) then click OK.

#### Step 3.3 – Coloring the Bubbles

• Click on any bubble to select all of them and right-click to open the context menu.
• Choose Format Data Series.
• Under the Fill option, tick Vary colors by point to multi-color the bubble.

#### Step 3.4 – Displaying the Chart in a Particular Style

• Click on the chart and the Chart Design tab appears.
• Choose any of the Chart Designs from the Chart Styles.

The final display of the chart should look like the below image.

⧭ Notes: (i) Highlight two data columns to create a bubble chart with two variables.

(ii) For 4 variables, use individual data series and denote them using Legends.

## Things to Keep in Mind

• Make sure the bubble sizes are proportional to their values. Excel usually auto-fits bubble sizes corresponding to their values, but if this is not the case, adjust the data to fit using the Square Root of the raw data.
