How to Work with Pivot Chart Styles in Excel
Excel provides several dozen chart styles on the Design tab. As with chart layouts, you select a chart style by clicking its button. Also as with chart styles, the Design tab provides space for only a subset of the available chart style buttons to be displayed at a time. You need to scroll down to see the other chart style options.
Excel 2007 and 2010 also provides several chart layouts on the Design tab of the Ribbon. You choose a chart layout by clicking its button. Do note that although the Design tab provides space for a limited number of chart layout buttons to be displayed at a time, you can scroll down and see other chart layout options, too.
