kdeeduplot API review (was Re: Moving kdeeduplot to kdelibs)

Hi,

Thanks for reviewing the API.  I agree with most of your suggestions, 
but I wanted to make one clarification:

> * virtual [left/right/top/bottom]Padding getters and setters (both virtual)

This is not padding between the axes and the content, it's padding 
between the edge of the widget and the axes.  Normally, these functions 
can be ignored because KPlotWidget will automatically compute these 
lengths based on what is to be shown along each axis.  For example, if 
the axis is showing both tick mark labels and an axis label, it needs 
more padding.  If it's just showing tick mark labels, it needs less 
padding, and if it's showing neither then it needs hardly any padding at 
all.

The padding setters are only needed externally if the user wants to 
override the automatic settings.

If the function names need to be clearer, I'd suggest 
[left|right|top|bottom]AxisPadding()
