A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
One technique you could try is to plot a 3-D column chart witha z-axis. When you have done this, select each series in turn, press Ctrl+1 to open the Format Series window, select Fill and set No Fill and then straight away select Picture for fill, click the Clip Art button and search for Bullet. Choose a simple round bullet shape and then select to apply this to the End of the column. Repeat this for each series of columns and the pictures on the tops of the columns should appear like scatter markers.
