4.2 Formatting Charts

Learning Objectives

  1. Apply formatting commands to the X and Y axes.
  2. Enhance the visual appearance of the chart title and chart legend by using various formatting techniques.
  3. Assign titles to the X and Y axes that clarify labels and numeric values for the reader.
  4. Apply labels and formatting techniques to the data series in the plot area of a chart.
  5. Apply formatting commands to the chart area and the plot area of a chart.
  6. Employ series lines and annotations to enhance trends and provide additional information on a chart.

You can use a variety of formatting techniques to enhance the appearance of a chart once you have created it. Formatting commands are applied to a chart for the same reason they are applied to a worksheet: they make the chart easier to read. However, formatting techniques also help you qualify and explain the data in a chart. For example, you can add footnotes explaining the data source as well as notes that clarify the type of numbers being presented (i.e., if the numbers in a chart are truncated, you can state whether they are in thousands, millions, etc.). These notes are also helpful in answering questions if you are using charts in a live presentation. We will demonstrate these formatting techniques using the column chart and stacked column chart from the previous section.

Lesson Video: X and Y Axis Formats

There are numerous formatting commands we can apply to the X and Y axes of the chart. Although adjusting the font size, style, and color are common, many more options are available through the Format Axis dialog box (see Figure 4.5 "Format Axis Dialog Box"). The following steps demonstrate a few of these formatting techniques on the Grade Distribution Comparison chart:

  1. Click anywhere along the X axis (horizontal axis) of the Grade Distribution Comparison chart on the Grade Distribution worksheet.
  2. Click the Home tab of the Ribbon.
  3. Change the font style to Arial. Notice that as the mouse pointer hovers over a font style, you can preview the change on the chart before you make a selection.
  4. Change the font size to 11 points and bold the font. The final appearance of the X axis is shown in Figure 4.24 "Formatted X Axis".
  5. Click anywhere along the Y axis to activate it.

Data Series Labels and Formats

Follow-along file: Continue with Excel Objective 4.00. (Use file Excel Objective 4.11 if starting here.)

Lesson Video: Data Series Labels and Formats

Adding labels to the data series of a chart is a key formatting feature. A data seriesA quantitative data set that is displayed graphically on a chart. Data sets are typically displayed in the form of columns or lines on a chart. is the item that is being displayed graphically on a chart. For example, the blue bars on the Grade Distribution Comparison chart represent one data series. We can add labels at the end of each bar to show the exact percentage the bar represents. In addition, we can add other formatting enhancements to the data series, such as changing the color of the bars or adding an effect. The following steps explain how to add these labels and formats to the chart:

  1. Click any red bar representing the College data series on the Grade Distribution Comparison chart in the Grade Distribution worksheet. Clicking one bar automatically activates all bars in the data series. If you click a bar a second time, only that bar is activated.
  2. Click the Format tab in the Chart Tools section of the Ribbon.

Follow-along file: Continue with Excel Objective 4.00. (Use file Excel Objective 4.13 if starting here.)

Lesson Video: Adding Series Lines and Annotations

The last formatting features we will demonstrate are adding series lines and annotations to a chart. To demonstrate these skills, we will use the Change in Health Care Spend Source stacked column chart. Series linesLines that are typically used in a stacked column chart to connect the data series between two or more stacks. are commonly used in stacked column charts to show the change from one stack to the next. AnnotationsNotes or comments that explain the nature and source of the data presented on a chart. are useful for clarifying the data presented in a chart or for identifying data sources. In addition to demonstrating these skills, we will review several of the formatting skills that were covered in this section. The following steps include the skills review as well as the new formatting features:

  1. Locate the Change in Health Care Spend Source chart on the Health Care worksheet. Activate the chart by clicking anywhere inside the chart perimeter.

  4. Activate the Y axis and apply the same formatting adjustments as stated in step 3.
  5. Add a Y axis title using the Rotated Title option. In the Format tab under the Chart Tools section of the Ribbon, select the first preset style option, Colored Outline - Black, Dark 1, in the Shape Styles group of commands. Then, in the Home tab of the Ribbon, change the font style to Arial and the font size to 14 points.
  6. Change the wording of the Y axis title to read Percent of Total Annual Spend.
  7. Activate the title of the chart by clicking it once. In the Format tab under the Chart Tools section of the Ribbon, select the first preset style option, Colored Outline - Black, Dark 1, in the Shape Styles group of commands. Then, in the Home tab of the Ribbon, change the font style to Arial.
  8. Click anywhere in the chart area to activate it.
  9. Click the Format tab in the Chart Tools section of the Ribbon and click the down arrow on the Shape Fill button. Select the Olive Green, Accent 3, Lighter 60% option on the color palette.
  10. Click anywhere on the plot area to activate it. Be sure not to click on a grid line.
  11. Click the Shape Effects button in the Format tab of the Ribbon. Place the mouse pointer over the Bevel option from the drop-down menu. Select the first option from the Bevel format list, which is the “Circle” bevel option.
  12. Click and drag down the top center sizing handle of the plot area approximately one inch (see Figure 4.39 "Adjusting the Size of the Plot Area").
  13. Click and drag up the bottom center sizing handle approximately three-quarters of an inch (see Figure 4.39 "Adjusting the Size of the Plot Area"). This step and step 12 are necessary to create space at the top and bottom of the chart to add annotations.

    Figure 4.39 "Adjusting the Size of the Plot Area" shows the Change in Health Care Spend Source chart prior to adding the series lines and annotations. Notice that the Ribbon has been minimized to improve the visibility of the chart. The remaining steps will focus on adding lines and annotations:

Integrity Check

Annotations and Axis Titles

Although adding annotations and axis titles can be a tedious process, doing so maintains a high level of integrity for your charts. People can misinterpret the message being conveyed by the chart if they make inaccurate assumptions about the values displayed. Axis titles and annotations help prevent readers from making false assumptions and ensure that readers see the most accurate representation of the message being conveyed by the chart.
