On top of +the obvious information of the depth it shows also the ascent and +descent rate compared to average (or recommendation). This information +is given using different colors. Dark red means the ascent or descent +rate is faster than average, dark green means slower than average and +yellow / light green is close to average. The depth graph includes also +depth readings for the peaks in the graph. Thus you should see the +depth of the deepest point and other peaks. Average depth is marked with +a horizontal red line. + +The air consumption graph displays the tank pressure and its change +during the dive. The air consumption takes depth into account so that +even when manually entering the start and end pressures the graph is not +a straight line. Similarly to the depth graph the tank pressure +gives you information of the SAC rate when using air integrated dive +computer. Same color coding is used with dark red being faster and dark +green slower air consumption than average. + +Water temperature is displayed with its own blue line with degree +markings placed adjacent to significant changes. + +It is also possible to zoom in the profile graph. This is done by the +left mouse button and zoom area can be changed by moving the mouse while +the button is pressed down. There is also a toggle zoom under the 'Log' +menu that changes the scale of the dive to fill the whole area, useful +especially for free divers. + +[[S_TecDiveProfile]] +Tec Information in Dive Profile +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The dive profile can include Tec settings. Enabling these is described +in chapter <<S_SettingUpPreferences,Setting up Preferences>>. Basically +you can include graphs of accumulated pO2, pN2, pHe. These graphs are +added below the profile data. On top of the profile the currently used +gradient factors are shown (e.g. GF 35/75). + +The graph can also include both the dive computer reported ceiling and +our calculated ceiling. Because of the differences in used algorithms it +is unlikely that both of these are the same. It is even quite common +that Subsurface calculates ceiling for non-decompression dives when the +dive computer was not in deco mode during the dive.
