Plot value 'mean()' example does not work.

[cdmiller]

When showing a dot plot in the Graph, the menu item "Plot Value" can accept constants, but the displayed example "Type an expression.e.g. mean()" does not work. Not sure where the bug is, but literally typing "mean()" does nothing.

Can we fix this to a working example? What would that be?
