The line chart illustrates the monthly sales of a shoe company between 2017 and 2018. The sales, ranging from $3,000 to $19,000, are plotted on the Y-axis.
In general, the sales for 2018 surpassed those of 2017, especially in May. However, there was a decline in the last three months of the fourth quarter compared to 2017. The sales trend for both years was somewhat similar: an increase in the first five months, fluctuations in the middle months, and a steady rise in the final three months of the year.
The sales for 2018 started at around $8,000 in January, peaked at approximately $18,000 in May, and then saw a significant drop in June, with a decrease of $9,000 from the previous month. A similar decrease occurred in October, with sales trailing by $9,000 compared to September, before gradually increasing in the last three months of 2018.
In 2017, sales steadily rose from January to May, from roughly $6,000 to $9,000, creating a $9,000 gap compared to May 2018, which was the highest among all the months. Following this growth period, sales fluctuated from May to August, with August recording the same revenue as May, before gradually rising in the last four months.
