h,x calc

The app calculates enthalpy in BTU/lb, dew point in °F and absolute humidity in gr/lb depending on temperature and relative humidity.

The values are also converted in metric-units.

The main view was expanded with a table, which hosts up to 12 pairs for graphical view inside the new hx-diagram.
There are two colored paths which show two different air flow path (7 points in red / 5 points in blue).

In the prefences there is a new setting, which allows to switch on and off the conection lines between the calculated linies inside the diagram.

The pre-defined setting of a reference temperature is used to calculate an index of how usefull is it to air the room with the outside air condition. If the dew point of the outside air temperature higher than the inside temperature (reference wall/room temp.) the water condenses on the cold wall surface and this leads to mold growth.

Addional the air pressure can be pre-defined in case the calculation should consider high or low pressure weather conditions or an environment of great height (mountains).

The pre-setting can be done via menu-button. After the changes are done, the app has to be restarted or the display orientation has be switched once to refresh the screen.
