Ah, the widgets underneath change depending on the type of function selected 
(e.g. see http://www.bluehaze.org/~david/polar.png).

KmPlot would stick with its line edit for formulas, and could have a button at

either be kformula if installed, or a custom one which has buttons for 
inserting a square-root or a power "^" symbol.
