Parts of a Chart
If a chart has more than one data series, you’ll usually need a way to identify the data series or data
points. A legend, for example, is often used to identify the various series in a chart. In this example,
the legend appears at the bottom of the chart. Some charts also display data labels to identify
specific data points. The example chart displays data labels for the Profit Margin series, but not for the
Income series. In addition, most charts (including the example chart) contain a chart title and
additional labels to identify the axes or categories.
The example chart also contains horizontal gridlines (which correspond to the values on the left axis).
Gridlines are basically extensions of the value axis scale, which makes it easier for the viewer to
determine the magnitude of the data points.
In addition, all charts have a chart area (the entire background area of the chart) and a plot area (the
part that shows the actual chart, including the plotted data, the axes, and the axis labels).
Charts can have additional parts or fewer parts, depending on the chart type. For example, a pie
chart (see Figure 5-6) has “slices” and no axes. A 5-D chart may have walls and a floor (see Figure 5-7).

Figure 5-7: A 3-D column chart.
Several other types of items can be added to a chart. For example, you can add a trend line or display
error bars.
