Sample Report 1

The presented bar chart provides a breakdown of telephone call durations in Australia, categorized into local, national and international, and mobile calls, spanning from 2001 to 2008, with values represented in billions of minutes.


Overall, it is evident that local calls consistently maintained the highest durations compared to other categories throughout the period, although their prevalence diminished slightly after a peak mid-decade. In contrast, both national and international, along with mobile call durations, displayed a continuous upward trajectory.


Initially, local calls escalated from 72 billion minutes in 2001 to a peak of 90 billion minutes in 2005, then retracted back to 72 billion minutes by 2008, forming a notable bell-shaped pattern. This demonstrates a significant fluctuation in local call usage, which although remaining dominant, showed a decline towards the latter part of the observed period.


On the other hand, national and international calls experienced a gradual but steady increase, climbing from 38 billion minutes in 2001 to 61 billion minutes by 2008. Mobile calls, starting at a relatively low 2 billion minutes in 2001, saw a substantial rise, culminating at 46 billion minutes by 2008. This marked expansion in mobile call usage particularly highlights a shift in communication preferences towards the end of the decade.

Sample Report 2

The bar chart delineates the duration of telephone calls in Australia, segmented by type—local, national and international, and mobiles—over the period from 2001 to 2008, measured in billions of minutes.


Overall, the trends indicate that while local call durations consistently exceeded other types, they began to wane mid-decade after an initial rise, unlike the steady increase observed in national and international, as well as mobile calls.


Local calls initially surged from 72 billion minutes in 2001 to a zenith of 90 billion minutes in 2005, before receding to their initial volume by 2008. This rise and subsequent decline sketches a bell curve, highlighting a peak mid-decade. The details reveal local call durations towering over the other categories each year, despite their eventual decline.


Conversely, national and international calls exhibited a more moderate but consistent ascent from 38 billion minutes in 2001 to 61 billion by 2008. The trajectory for mobile calls was even more pronounced, starting from a mere 2 billion minutes and expanding substantially to 46 billion minutes by the end of the period.



Sample Report 3

The bar diagram illustrates the total number of minutes spent on telephone calls in Australia from the year 2001 to 2008, where the calls are categorised into three groups, local, national and international, and mobile. Units are measured in billions of minutes.


Overall, though the gap between the time spent on local calls and other modes of telecommunication kept falling over the time, annual used minutes on local calls always remained the highest throughout the period. Meanwhile, time spent on both national & international and mobiles continued increasing consistently, but the local call time started declining gradually from the middle of this seven-year range.


The local call time experienced the highest trend throughout the period, starting from 72 billion minutes in 2001 to reach a peak of 90 billion minutes by 2005, this trend then slipped back to 72 billion minutes in 2008. As for national and international the popularity of this types of calls increased slightly, beginning from 38 billion minutes to finish at 61 billion minutes by the end of the period.


On the other hand, mobile calls witnessed a slight growth initially, beginning the period with 2 billion minutes merely. Having experienced a gradual increase until 2005 with around 12 billion minutes, mobile call minutes then rocketed to 46 billion minutes by the end of this period.
