Bug 89186

Version:           1.0.0_devel (using KDE 3.3.0, compiled sources)
Compiler:          gcc version 3.3.2
OS:                SunOS (sun4u) release 5.8

The "Change data file" function is absolutely GREAT and saves an incredible amount of time. However, there is one relatively simple thing that it could do to be much more efficiently.

Imagine you are comparing file1.dat with file2.dat. You will have created the vectors, curves, equations, etc... that you need. Now you want to see whether configuration 3 (data in file3.dat) is better than configuration 2 (file2.dat). To replace the vectors coming from file1.dat with the equivalent ones from file3.dat, you have to manually look for the vectors coming from file1.dat, select them and only them and then Select file3.dat in the file selector and hit "Apply". The dialogs being non-modal, if you have a big screen you may make it. But it would be much simpler to have e.g. a QComboBox between the top label and the vector list showing "All vectors from file1.dat" and "All vectors from file2.dat". If you select one of these files, the selection in the vector list would be updated to match this choice. Then you can proceed as usual. (Maybe the U.I. can be made better ?)
