How to Draw Some Useful Charts Not on Excel Menus
The resources below show that one can use Excel for graphs that are not on its menus. However, it is easier to use software designed to draw these graphs if you know the necessary language. R, an implementation of the S language, is open source software that is extremely powerful and is available at no cost from http://www.r-project.org. 1 BOX PLOTS
A number of websites give instructions for drawing box plots using Excel but most do not include outliers. Therefore, I prefer the utility of Jon Peltier since it does handle outliers. Sites include:
2 DOT PLOTS
