Excel provides a rich set of options for formatting the background areas of your charts— including the plot area, the chart area, and the walls and floors of three-dimensional charts. You can also apply these formatting options to legends, to the background areas of text objects (titles and data labels), and to certain kinds of chart markers—including columns, bars, pyramids, cones, cylinders, areas, bubbles, pie slices, and doughnut bites.
You can access all the formatting options described in this section from the Fill Effects dialog box. (To get there, select the chart element in question, and then choose the first command on the Format menu.) On the Patterns tab, click the Fill Effects button.
