Profile: dynamically allocate plot pressure data

All accesses to the pressure data were converted to use functions.
Therefore it is now rather trivial to dynamically allocate the
pressure array and just change the functions.

The only thing to take care of is the idiosyncratic memory
management. Make sure to free and copy the buffer in the
appropriate places.
