AxSpan draggable not implemented

See original GitHub issue

It looks like PlottableAxSpan has draggable api, but not implemented. Additionaly it will be usefull to have OnChanged(double newValue) events for both borders, which rises on end drag by user.

Hi @swharden. Thanks for this big amout of work. I checked this, have some ideas that to add and refactor. Try to make this soon. There are one thing i really can’t solve. Dragging axises or spans looks much more laggy then paning. Check the code, it have the same math complexity. Profiled, also nothing specal. But dragging goes like 3 fps, when pan or zoom goes smooth.

Maybe anti-aliasing isn’t turned off while dragging portables?

I tryed that too, the same result.

We should properly alias while dragging
