Display inert gas tissue pressures relative to ambient inert gas pressure (horizontal grey line).
Tissue pressures are calculated using the Bühlmann ZH-L16 algorithm and are displayed as lines ranging from
green (faster tissues) to blue (slower tissues).
The black line, graphed above the ambient pressure, is the maximum allowable tissue supersaturation (pressure limit) derived
from the gradient factors specified in the *Preferences*. For
divers involved in planned decompression diving, efficient rates of offgasing are obtained with tissue pressures
between the ambient inert gas pressure (grey line) and the pressure limit (black line). This display is a representation
of the tissue pressures during the whole dive. In contast, the xref:S_gas_pressure_graph[Gas Pressure Graph] in the *Information Box* on the *Dive Profile*
is an instantaneous reflection of tissue pressures at the moment in time reflected by the position of the cursor on the dive profile.

Gradient Factor settings strongly affect the calculated ceilings and their depths.
For more information about Gradient factors, see the section on xref:S_GradientFactors[Gradient Factor Preference settings]. The
currently used gradient factors (e.g. GF 35/75) are shown above the depth profile if the appropriate toolbar buttons are activated.

=== Filtering the dive list
The dives in the *Dive List* panel can be filtered, that is, one can select only some
of the dives based on their attributes, e.g. dive tags, dive site, dive master, buddy or protective
clothing. For instance, filtering allows one to list the deep dives at a particular
dive site, or otherwise the cave dives with a particular buddy.
To open the filter, select _Log -> Filter divelist_ from the main menu. This opens the
_Filter Panel_ at the top of the _Subsurface_ window. Three icons are located at the top
right hand of the filter panel. The _Filter Panel_ can be reset
(i.e. all current filters cleared) by selecting the *+*. The _Filter Panel_ may also be
minimised by selecting the middle icon. When minimised, only these three icons are shown.
The panel can be maximised by clicking the icon that minimised the panel. The filter may also be
reset and closed by selecting the button with the flag.
An example of the _Filter Panel_ is shown in the figure below.
image::images/Filterpanel.jpg["Figure: Filter panel",align="center"]
Four filter criteria may be used to filter the dive list: dive tags, person (buddy / dive master), dive site
and dive suit, each of which is represented by a check list with check boxes. Above
each check list is a second-level filter tool, allowing the listing of only some of
the attributes within that check list. For instance, typing "_ca_" in the filter
textbox above the tags check list results in the tags check list being reduced
to "_cave_" and "_cavern_". Filtering of the check list enables the rapid finding
of search terms for filtering the dive list.
To activate filtering of the dive list, the check box of at least one item in one of
the four check lists needs to be checked. The dive list is then shortened to include
only the dives that pertain to the selection criteria specified in the check lists.
The four check lists work as a filter with _AND_ operators: there is no _OR_ operator.
One can therfore search for _cave_ as a tag AND _Joe Smith_ as a buddy; but NOT
for dives with either _cave_ as a tag OR _Joe Smith_ as a dive buddy.
