Line graph — Enquiries received by a tourist information office, January to June

The line graph plots the number of enquiries a city's tourist information office received through three channels, namely personal visits, telephone calls and letters or emails, in the first half of a year.

Overall, enquiries made in person and by telephone increased substantially, the former going from the least used method to the most used. Written enquiries, by contrast, were the only type to decline.

In January, only 430 enquiries were made in person, fewer than half the 880 received by telephone. Visits then rose month after month, to about 790 in March and 1,190 in April, by which point they had overtaken telephone calls. They went on to reach 1,870 in June, more than four times their January level. Telephone enquiries followed a less regular path: after dipping to 790 in February, they recovered to around 1,000 and stayed flat between March and April, before climbing steeply to 1,620.

Enquiries by letter or email began at 760 and hovered around 700 for the first three months. From March onwards, however, they dropped steadily, to roughly 560 in April and 370 in June, about half the initial figure. Consequently, the three methods, which had been separated by only 450 enquiries in January, were spread across a range of 1,500 by the end of the period.
