What is Whisker Charts?

Whisker charts are data visualizations best used for statistical analysis and to show the distribution of a dataset. The “whiskers,” shown as lines that extend vertically from the boxes, denote variability outside the upper and lower quartiles. This type of chart is also referred to as a box and whisker plot.

Whisker charts are one of many types of data visualizations used to organize and present data in a way the audience can understand and take action on. To ensure visualizations have real business value, it’s important to know which types of visualizations are best suited for a given data set.
