Where they differed most
A shop has 14 months of weekly revenue and wants to see whether sales are seasonal. In under 90 words, say which chart to build, which fields go on which axis, and one thing this chart will NOT tell them.
Build a **line chart** with **weeks** (or months) on the x-axis and **revenue** on the y-axis. This shows revenue trends over time, revealing seasonal peaks or troughs. One thing this chart will **not** tell them is whether the seasonality is statistically significant—it only shows visual patterns, not proof that the variation isn’t random.
Build a **line chart**. Place the "Week/Date" field on the **X-axis** and "Revenue" on the **Y-axis**. This will visually highlight repeating peaks and troughs across the 14 months, making seasonal patterns easy to spot. However, this chart will NOT tell them the **underlying cause** of these fluctuations (e.g., whether a revenue spike is due to a specific holiday, a successful marketing campaign, or an external economic factor).
