Version: (using KDE 4.3.2) OS: Linux Installed from: Debian testing/unstable Packages Create a simple plot with the following data: ----------- x y 1 1 2 3 ----------- (use the data wizard, say that first row is the column title) Then Tools/Change data file... Use the same file (or one with same structure) => Error like fields x, y are not available. Indeed there is no way to specify the structure of the file, but maybe it should be guessed from the original one ? Tested with 1.7 (debian old binary, sic) and latest svn from kde4 port branch. Cheers, and go on, it is really a great tool !
Of course a possible work-around is to avoid the use of column names in the files, but... I don't really like to have them named 1,2,3,...
I believe it should work if you configure the ASCII datasource from Settings -> Configure Kst -> Data Sources tab -> Data source: ASCII File Reader to always accept files matching your name pattern (e.g. *.dat) and configure *.dat to have that specific format. At least it used to work with older versions, I haven't checked recently.
It would seem worthwhile to at least have a Configure... button next to the selected file, so that the user can override the default configuration. The problem with guessing the file structure from the old one is that the input vectors may come from several different files, all with different configurations.

Whaou, you are very reactive, thanks a lot ! I'll test that as soon as I find some time to build it
