Line charts are ideal for displaying trends over time, making them suitable for showing monthly sales trends.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Histogram
Why it's wrong here
Histograms show distribution of a continuous variable, not trends over time.
- ✗
Pie chart
Why it's wrong here
A pie chart encodes data as proportional slices of a circle, comparing parts to a whole at a single point in time, but it cannot display a continuous trend across monthly intervals over three years. The requirement demands a time-series visualisation where the x-axis represents sequential months and the y-axis shows sales values. This option is tempting because pie charts effectively show category proportions, such as each month’s share of total annual sales, but that static snapshot does not reveal upward or downward movement over time.
- ✓
Line chart
Why this is correct
Line charts effectively show trends over time.
- ✗
Scatter plot
Why it's wrong here
Scatter plots show correlation between two variables, not a single trend over time.
