A company needs to visualize monthly sales revenue for the past five years to identify seasonal trends. Which chart type is most appropriate?
⚠ Common exam trap
DA0-002 often tests the appropriate chart type for time series data; candidates may choose bar or pie charts, but line charts are best for showing trends over time.

Correct answer & explanation
✓
Line chart with months on the x-axis and revenue on the y-axis
A line chart with months on the x-axis and revenue on the y-axis is ideal for visualizing monthly sales revenue over five years to identify seasonal trends. It clearly shows patterns, trends, and seasonal fluctuations over time, making it easy to compare year-over-year performance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Line chart with months on the x-axis and revenue on the y-axis
Why this is correct
A line chart plots revenue against a continuous time axis, so five years of monthly points form an unbroken series where recurring peaks and troughs are directly visible. Months on the x-axis preserve chronological order, which is what exposes the seasonal pattern the company needs.
- ✗
Stacked bar chart showing each year as a segment
Why it's wrong here
Stacking each year as a segment sums the years within each month, so the monthly total and its seasonal shape are obscured by cumulative segments. Stacked bars suit showing how component categories contribute to a whole, such as revenue split by product line per month.
- ✗
Scatter plot with revenue vs. month number
Why it's wrong here
Plotting revenue against month number treats time as an unordered numeric axis, so points scatter without a continuous sequence, hiding the repeating seasonal pattern. Scatter plots suit correlation between two continuous variables, such as revenue versus advertising spend, not cyclical trends across years.
- ✗
Pie chart for each year showing revenue distribution
Why it's wrong here
Separate pie charts show each year's monthly share of that year's total, discarding absolute revenue and preventing comparison of the same month across five years. Pie charts suit part-to-whole composition at a single point in time, such as one year's revenue by region.

Variation 1. A company needs to visualize the trend of monthly sales revenue over the past two years. Which chart type is most appropriate?
easy- A.Bar chart
- B.Scatter plot
- ✓ C.Line chart
- D.Pie chart
Why C: A line chart is the most appropriate for visualizing the trend of monthly sales revenue over time because it plots data points connected by lines, clearly showing the direction and pattern of change across a continuous time series. The x-axis represents time (months), and the y-axis represents revenue, allowing for easy identification of upward or downward trends, seasonality, and fluctuations. Unlike other chart types, line charts are specifically designed to highlight trends and changes over intervals.
