Editing and Enhancing Chart Information
The chart that Word 2010 adds to your document will be fairly straightforward, without much formatting or color. After you create the basic chart, you can add to, edit, and enhance your chart in a number of different ways. Begin by clicking the chart you want to change; the contextual Chart Tools appears automatically along the top of the Ribbon. You use the Chart Tools, shown in Figure 16-13, to change the chart layout, choose a chart style (including colors and shadow effects), add titles and labels, change the look of the background and axes, and much more. The sections that follow show you how to add specific items to your charts to make them easier for readers to understand.

Choosing a New Chart Layout
If you spend some time working on a chart and just don’t feel it portrays what you want to convey, you can easily switch chart types by applying a new layout to the chart. A chart layout is like a template—complete with a legend style, data labels, and more—that you apply to the chart you’ve already created. You can choose a layout for your chart when you want to save yourself the time and trouble of choosing a number of chart options individually.
To apply a chart layout, click the chart to select it, and then on the Chart Tools Design tab, click the More button in the lower-right corner of the Chart Layouts gallery to display the whole collection of layouts (see Figure 16-14). Simply click the layout to apply it to your chart.

Applying a Chart Style
Word includes another design feature that makes creating a professional chart much easier. The Chart Style gallery includes dozens of visual styles that you can apply to a chart in your document. Chart Styles include:
Outline style and color
To apply a chart style, select the chart, and then on the Chart Tools Design tab, click the More button in the lower-right corner of the Chart Styles gallery and then choose the style you want from the displayed collection (see Figure 16-15).

Adding a Chart Title
Not all charts need titles, but a chart title can help readers understand the “big picture” you’re trying to communicate. To add a title to your chart, click Chart Title in the Labels group on the Layout tab of the contextual Chart Tools. In the gallery, choose whether you want the title to be centered on the chart or placed above the chart. (If you decide later that you want to move the title, you can simply drag it to the point on the chart where you want it to appear.) Centered Overlay Title enables the chart to be displayed at maximum size (which is important if you have a fairly complex chart), while Above Chart reduces the chart size slightly to make room for the title. Experiment with each choice to find the one that’s right for your chart.
Working with Axes
The axes of your chart are important in that they set up the structure for the way in which data is displayed. You can use two different tools in the contextual Chart Tools to work with axes. Both are found on the Layout tab.
If you want to instruct Word to display the title of an axis, click Axis Titles in the Labels group. To add an axis title to your chart, begin by clicking Axis Titles and pointing to the axis you want to change (Primary Horizontal Axis or Primary Vertical Axis). When you point to the Horizontal Axis selection, choose Show Title Below Axis to add the title text box to the chart. (You can click and drag the title box anywhere on the chart you’d like it to appear—but be sure to keep it close to the axis so your readers will understand what it refers to.) If you select Primary Vertical Axis, you will see three choices: Rotated Title, Vertical Title, and Horizontal Title. Select your display choice, and then simply click in the text box and type the text for your axis title.
If you want to change the way in which information is displayed along the axis, you can choose Axes in the Axes group. When you click the Axes tool, a list appears, offering Primary Horizontal Axis and Primary Vertical Axis as options. Choose the axis you want to change, and another set of choices appears (see Figure 16-16). For the horizontal axis, your choices involve whether the axis runs right to left (or vice versa) and where the data labels appear. For the vertical axis, you can choose the value increments you want to appear on the axis (thousands, millions, or billions).
Figure 16-16 Choose the axis you want to change and make your selection from the gallery.
If you want to further control the axes in your chart, you can choose More Primary Vertical Axis Options or More Primary Horizontal Axis Options at the bottom of each of the respective galleries. To further refine how your axes appear, you need to display the Format Axis dialog box, as shown in Figure 16-17. In this dialog box, you can choose the increments for the values on the vertical axis, set the tick mark type, and determine the placement of the chart floor. In the Format Axis dialog box for the horizontal axis, you can also set axis type and tick mark settings, and choose where the vertical axis crosses the horizontal axis. Additionally, in both dialog boxes, you can choose line color and fill, shadow, and 3-D effects for the axes.
Figure 16-17 You can choose additional options for the axes in your chart by using the Format Axis dialog box.
Add Gridlines and Trendlines
If you’re working with complicated charts that have multiple data series, gridlines can help clarify the comparisons and conclusions you want readers to draw from your chart. Select the Gridlines tool in the Axes group on the Chart Tools Layout tab. Then click either Primary Horizontal Gridlines or Primary Vertical Gridlines. Both choices give you the option of selecting major gridlines, minor gridlines, or major and minor gridlines.
Displaying and Positioning a Legend
Word assumes that you want a legend for your chart when you first create it. If you don’t feel the legend is needed and want to have more space for your chart, you can remove the legend by clicking Legend in the Labels group on the Layout tab (available in the Chart Tools). When you choose None (the first option on the list), the legend is hidden. The chart is enlarged to fill the space the legend previously occupied.
You can also control where the legend is placed in the chart by clicking the Legend tool in the Labels group. A range of options appears from which you can choose, as shown in Figure 16-18.

Working with Data Labels
Data labels are helpful when you need to give the reader further clues about which data items go with which series or category. Word gives you the ability to add several different kinds of data labels to your charts. You might want to add percentages to pie slices, for example, or category labels to stacked bars. Click Data Labels in the Labels group to display a list of placement choices for the data labels on your chart.
By default, Word displays data values in the pie slices or bars of your chart. You can change the type of information displayed and add special features such as color, shadows, outlines, and 3-D options by choosing Data Labels in the Labels group and clicking More Data Label Options. In the Format Data Labels dialog box (see Figure 16-19), you can choose the label contents you want to display (series name, category name, value, or percentage).

One more way to ensure that readers get the connection between your data trends and the categories being plotted: you can use the Legend Key feature to add small legend tags to the left of each data label. Readers will be able to see at a glance which items relate to the categories in your chart legend.
