Box-and-whisker
One dimension on the X axis groups the data into categories. One measure on the Y axis provides the raw values. The chart computes the distribution statistics internally.Reading a boxplot

|---|---|
| Box | Interquartile range — 25th to 75th percentile |
| Center line | Median (50th percentile) |
| Whiskers | Extend to min/max within 1.5× the IQR |

Data structure
Boxplots require raw, row-level data — each row is one observation. Do not pre-aggregate before using a boxplot; the chart engine computes the distribution itself.- X axis — the grouping dimension (e.g. product category)
- Y axis — the measure to distribute (e.g. sale price)
