Hi Jeremy and all,
I'm wondering how difficult it would be to add dataset namespaces.
Currently if a file is imported with a data row/column label that's the
same as a data label in a previously imported file, the new data
row/column will clobber the old one from the previous file. In the use
case of multiple experimental conditions resulting in files with the
same format, that means the researcher has to go into each file and add
some sort of unique id to the label of each row of data if he or she
wants to display multiple datasets in the same Veusz graph.
Additionally, if two imported files usually have different labels but in
rare cases have the same label, one of the data sets will clobber the
other without the researcher knowing it (no error or warning occurs -
the old data is silently overwritten).
Hence if the data labels from one file could have namespaces designated
by the user, perhaps defaulting to the filenames, it could be very
useful for researchers dealing with data in multiple files. I'm not sure
how much reworking of the code that might take though - could be
substantial. Anyway, just a suggestion - but I would at minimum advocate
warning a user if his or her data is going to be overwritten.
Cheers, Gavin
