The line chart details the frequency of requests in person, by letter/email, and by telephone at a UK tourist office in the first 6 months of a given year.
Looking from an overall perspective, it is readily apparent that n-person requests increased from the least to most common over the period, overtaking telephone, which also rose. Information requests by email and letter declined and were by far the least frequent by the end of the time surveyed.
In January, in-person information requests were the lowest of all 3 categories at approximately 420. In contrast, written requests and telephone calls stood at 770 and 900 in turn. By mid-March, in-person questions (1,000) had surpassed other queries, an upwards trend that persisted and culminated at 1,900 to finish the period.
In comparison, telephone requests fluctuated between 800 and 1,000 until the beginning of April prior to growing sharply to end just behind in-person requests at 1,600. Letter and email requests fell marginally until March (to 700), before a steep drop, and a leveling off at 400 from May to June
