Description Nicolas Brisset 2004-09-09 18:00:57 UTC 
Version:           1.0.0_devel (using KDE 3.3.0, compiled sources)
Compiler:          gcc version 3.3.2
OS:                SunOS (sun4u) release 5.8

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.

I think this is no longer really useful, as we can achieve the same effect easily with an equation + multiple edit of curves to change all the curves using the original vector to use the new one.
This would have been useful before we had multiple edit, but now I'd say it's better to spend time on other, more important features.
