Today at work I was seething with rage: after working for some hours on some data, I lost the complete graph I had created (using some time consuming tricks to circumvent some incabalities of the program)! How that? Well, I know that with complex layouts the programs tends to crash sometimes and so I do save often. But it happened today, that the program gave just an error message on saving and wrote 0 bytes to the file, so that no working version has been left. I'm not able to send a file for testing to the support as I don't have it anymore!
But doing a “Save As…” anytime is really not convenient! (Maybe I should try using a WebDAV connection to a subversion repository with autoversioning turned on? Nice idea, just haven't tried if this is working yet…)
So you ask which application I use? Diadem by National Instruments. It has an unusual GUI, but it can access the database used by NI directly (all other programs can just using SQL commands…) and it has no problem with large data sets (analysing long term measurements can easily lead to datasets with more than a million points). The biggest problem I encounter are with creating and editing the graphs. Using many graphical elements leads to problems sometimes (not always easily reproducible) and the graphical cabalities are just developing so you have to use some tricks sometimes (which may increase the stability even further).
