Use this procedure to change colors, apply a texture or pattern, or change the line width or border style for data markers, the chart area, the plot area, gridlines, axes, and tick marks in 2-D and 3-D charts, trendlines and error bars in 2-D charts, and the walls and floor in 3-D charts.
Double-click the chart item you want to change.
If necessary, click the Patterns tab, and then select the options you want.
To specify a fill effect, click Fill Effects, and then select the options you want on the Gradient, Texture, or Pattern tabs.
Note: Formatting applied to an axis is also applied to the tick marks on that axis. Gridlines are formatted independently of axes.
