Hi, Recently after borrowing a XDeep bottom timer I started using subsurface instead of my paper logbook and it works perfectly on my favorite OS. The representation of the recorded dive data is fantastic and it is really nice to be able to add bottle changes by hand. So first of all, thank you all for working on subsurface.
However, once I returned the bottom timer and I had to manually add dives I ran into the issue that it is really hard (almost impossible) to enter the dive data correctly. I think some software changes are required, but maybe I am just doing something wrong. Let me explain. After a dive my simple bottom timer gives me: total dive time, max depth, average depth and water temperature. When using Subsurface v4.1 (compiled myself against the v4.1 git tag) I find it is impossible to add my dive data (for instance) a 77 minute dive with a max of 9.7 meters and an average of 6.8 meters. The movable points in the graph snap to whole meters, so setting a max depth of 9.7 is not possible; I would have to settle for 10 meters. To set the 77 minutes I have to move the last movable point to say 75 minutes to make the surface point end at (about) 77 minutes. Now, I don't know the exact profile I've been diving; it will typically have many ups and downs as I dive in cave's a lot. There is no way for me to modify the average depth other than to insert a shallow level for about half the dive manipulate the average depth that way (either be calculating the required level and time on a calculator or using trial and error). All and all it is a cumbersome way of adding the correct info of my dives and I never get the 'exact' numbers. Alternatively, I have been altering the xml logbook file directly. Setting the duration attribute of the dive node to "77:00 min", removing all sample nodes and changing the max and mean attributes of the depth node to the desired values of respectively "9.7 m" and "6.8 m". At least when loading this edited file, subsurface shows a dive profile with the correct max depth, average depth and dive time values by 'automatically' adding a shallow level at 3.2 meters from about 45 minutes. This way the statistical data is correct, but the graph does (of course) in no way represent the actual dive profile. Personally I think to add a dive manually, you should be able to enter the data numerically in stead of having to manipulate the point in the profile (or editing the logbook xml file). Also I think no graph should be shown as there is no way of determining the actual profile and all representations will be false by default. (I hope I don't offend anyone as it looks like some of you have spend quite some time building the otherwise great graph editing interface) I think I could make some changes myself to the code in order add manual dives numerically and not show an graph, but I would really like you opinions before I even start working on it; maybe I am just missing something. Let me know what you think, Onno _______________________________________________ subsurface mailing list [email protected] http://lists.hohndel.org/cgi-bin/mailman/listinfo/subsurface
