Agreed, I was thinking about that as well. I'd prefer replacing label with tickLabel and I wouldn't mind the extra typing :-) > 2) Should we add RightAxis and TopAxis, which can be independent of > BottomAxis and LeftAxis?

Yes, per default right and top axes labeling should be turned off, tick mark drawing is on by default. > 3) Control over whether to show axes, tickmarks, and tick labels should > be moved to KPlotAxis, so that it can be controlled separately for each > axis.

Maybe instead of using DataRect in > KPlotWidget, we should keep the limits in KPlotAxis as well > (KPlotAxis::min() and max()). Yes, that's what I had in mind. We can even "outsource" the axis drawing code to each axis object and let the plot widget simply call each axis to draw itself. Technical Design Question: If we move the drawing and padding rendering functionality to each axis, we could provide the means that a user can subclass an axis and provide his own axis drawing implementation. Do you think this is reasonable? That would mean that axis objects are access rather like: plotWidget->LeftAxis()->setTickLabelFormat(...) and we need to provide extra functions like: MyOwnAxis * axis = MyOwnAxis(); plotWidget->setLeftAxis(axis); // assigns user define axis plotWidget->resetLeftAxis(); // assigns default axis What do you think?
