Imagine you want to compare experiments performed at different times by superimposing curves, and that moreover there are some simple unit conversions to perform.
Sure, you can create equations and new curves using them. But that's a lot of trouble for such common operations.

I think adding a "Shift" spinbox (with a QDoubleValidator) in the "Edit Vector" dialog would be very handy. It would just add the selected/typed value to all elements of the vector and redraw all plots using it.
Similarly, we could add a "Scale" spinbox to multiply all elements.
