Given are two charts comparing and contrasting the proportion of buses arriving punctually, considering both actual and target results, along with the number of complaints received from passengers over a period of five years.
Overall, it is lucid that while the percentage of anticipated targets had a downward trend over time, the proportion of real results consistently fluctuated after five years, showing no clear pattern. Additionally, despite the initial drop, the quantity of complaints at this bus company had an increasing trend over five years.
To commence with, in 1990, when the proportion of buses arriving on time in anticipated achievements was 86%, it stabilized in the next year. After that, this figure gradually dropped to 85% in 2001, remained unchanged in the next day and fell tediously at over 84%. Meanwhile, the statistic of buses arriving punctually in actual results in 1999 was 85%, which was 1% lower than the target one. In the next 4 consecutive years, this number fell drastically to 82%, then dramatically surged to nearly 85% in 2003.
On the other hand, in 1999, the quantity of complaints started off nearly 70, then surged immensely to 100 in the next year. After that, this number dropped to over 80, and gradually increased to 120 in the next two years, when it hit its peak
