The graph illustrates the number of interrogations directed to the Tourist Information Centre over a period of six months in 2011.
In general, the first half of the period witnessed the dominance of telephone enquiry, while in person investigation was the most common method in the second half of the period. It is also noticeable that the most significant change belonged to face to face interrogation.
From January to March, ranked first in the graph was telephone, whose number fluctuated between 900 and 1000 enquiries. In contrast, the figure for letter/email remained just under 800 and it was surpassed by in person method in early March.
During the four remaining months of 2011, the number of face to face enquiries increased dramatically and took over the first rank which was held by telephone to reach the peak of approximately 1900. However, the figure for letter/email went on a downward trend until it reached a plateau at around 400 enquiries in May.
