You can add AutoShapes and other drawing objects only to a chart. You cannot add them to the datasheet.
On the Drawing toolbar, click AutoShapes, point to a category, and then click the shape you want.
To insert a shape with a predefined size, click the chart.
To insert a shape with a different size, drag the pointer to make the shape the size you want.
To maintain the shape's width-to-height ratio, hold down SHIFT while you drag the pointer.
To draw a circle or square, click Oval or Rectangle on the Drawing toolbar, and then click the chart.
To add color, change borders, rotate, or add shadow or 3-D effects to a shape, select the shape, and then use the tools on the Drawing toolbar.
