The graph presents 'passanger'(bladortog, slowo jest passenger) revenue and the 'perecentage' (blad ortog) of trains arriving on time from Cruiseline for each quarter of (tutaj dalabym przedimek 'a') two year period, 2[tel].
Cruiseline ‘s profits rose steadily from (przedimek) first quarter of 2005 to (przedimek) second quarter of 2006 with only one change in the 4th quarter when the earnings dropped from a previous level of 300'mln (sprawdz czy to tak sie pisze) (daj w calosci million) to 290 'mln' (popraw).
Profits from 'a' (czy nie wiesz o czym mowa, jak tak to 'the') factory were the highest with a record profit of ~$325 million in the second quarter of 2006, but started decreasing rapidly in the third quarter to a final value of around $225 'mln' (million) at the end of the year.
Percentage of the trains arriving on time was the highest at the beginning of 2005 and it 'was quite' (zrob to inaczej, daj 'remained') stable for one and half year before dropping suddenly in (przedimek) 3rd quarter (daj tutaj rok, bo nie jest jasne o ktorym mowa) to 70%. The percentage soon rose slightly to 75%. (trains on time?)
The graph shows the percentage of trains arriving on time which is 'positevely' (blad ortog) correlated with 'passanger' (blad ortog) revenues. That (napisz co? correlation? point?) can be seen mostly in the third quarter when (przedimek) percentage of trains arriving on time 'plummeted suddenly' (zla kol slow, daj suddenly plummeted.)
