# Present your data in a bubble chart

A bubble chart is a variation of a scatter chart in which the data points are replaced with bubbles, and an additional dimension of the data is represented in the size of the bubbles. Just like a scatter chart, a bubble chart does not use a category axis — both horizontal and vertical axes are value axes. In addition to the x values and y values that are plotted in a scatter chart, a bubble chart plots x values, y values, and z (size) values.

You can use a bubble chart instead of a scatter chart if your data has three data series that each contain a set of values. The sizes of the bubbles are determined by the values in the third data series. Bubble charts are often used to present financial data. Different bubble sizes are useful to visually emphasize specific values.

To create a bubble chart, arrange your data in rows or columns on a worksheet so that x values are listed in the first row or column and corresponding y values and bubble size (z) values are listed in adjacent rows or columns. For example, organize your worksheet data as shown in the following picture.

In this bubble chart, the number of products is displayed along the horizontal axis, the sales amounts are displayed along the vertical axis, and the market share percentages are represented by the size of the bubbles.

Consider using a bubble chart when your data includes the following:

• Three values per data point    Three values are required for each bubble. These values can be in rows or columns on the worksheet, but they must be in the following order: x value, y value, and then z value.

• Multiple data series    Plotting multiple data series in a bubble chart (multiple bubble series) is similar to plotting multiple data series in a scatter chart (multiple scatter series). Scatter charts use sets of x values and y values, but bubble charts use sets of x values, y values, and z values.

When you create a bubble chart, you can choose to display bubbles in 2-D format or with a 3-D effect.

### Create an elaborate bubble chart

So, how did we create this bubble chart? The following procedure will help you create a bubble chart with similar results. For this chart, we used the example worksheet data. You can copy this data to your worksheet, or you can use your own data.

1. Copy the example worksheet data into a blank worksheet, or open the worksheet that contains the data that you want to plot in a bubble chart.

To copy the example worksheet data

1. Create a blank workbook or worksheet.

2. Select the example in the Help topic.

Note: Do not select the row or column headers.

Selecting an example from Help
3. Press CTRL+C.

4. In the worksheet, select cell A1, and press CTRL+V.

Note: Make sure that your worksheet has at least four rows or columns of data. When you create a bubble chart from three or fewer rows or columns of data, the chart does not plot the bubbles correctly.

2. Select the data that you want to plot in the bubble chart.

Note: It is best not to include row or column headings in the selection. If you select the headings with your data, the chart may produce incorrect results.

3. On the Insert tab, in the Charts group, click the arrow next to Scatter Charts.

2. For Maximum, type the number that you want.

For our bubble chart, we typed 80000.

14. In the Format Axis dialog box, click Number.

15. Under Number, in the Decimal places box, type 0 (zero), and then click the down arrow in the upper-right corner, and click Close.

16. To apply a special formatting effect to the plot area, chart area, chart title, or vertical axis of the chart, click that chart element, or select it from a list of chart elements (Format tab, Current Selection group, Chart Elements box), and then do the following:

1. On the Format tab, in the Shape Styles group, click the More button next to Shape Effects.

2. Click the effect that you want to use.

2. Click the theme that you want to use. (Hover over each theme to see a preview of how the theme will appear when applied to your chart.)

You can save the chart as a template that you can use as the basis for other similar charts. For more information, go to Save a custom chart as a template.

For more information about how to apply a chart template, see Save a custom chart as a template.

Note: A chart template contains chart formatting and stores the colors that are in use when you save the chart as a template. When you use a chart template to create a chart in another workbook, the new chart uses the colors of the chart template — not the colors of the document theme that is currently applied to the workbook. To use the document theme colors instead of the chart template colors, right-click the chart area, and then click Reset to Match Style on the shortcut menu.
