Box plots, also known as box and whisker plots, display data pooled from multiple sources into one visual, helping you make datadriven decisions. Use a box plot to visualize how data is distributed across an axis or over time, for example flights delayed over a sevenday time period. Typically, a box plot details information in quarters:
 Minimum – The lowest data point excluding outliers.
 Maximum – The highest data point excluding outliers.
 Median – The middle value of the dataset.
 First Quartile – The middle value between the smallest number and the median of the dataset. The first quartile doesn't include the minimum or the median.
 Third Quartile – The middle value between the largest number and the median of the dataset. The third quartile doesn't include the maximum or the median.
Outliers are extreme data points that aren't included in the calculation of a box plot's key values. Because outliers are calculated separately, their data points don't appear immediately after a box plot is created. Box plots display up to 10,000 data points. If a dataset contains more than 10,000 data points, a warning appears at the upperright corner of the visual.
Box plots support some calculated fields, but not all. Any calculated field that uses a window function, for example avgOver, results in a SQL error.
The following screenshot shows a box plot.
Procedure
Create a basic box plot visual
 Click Visualize (the bar chart icon in the tool bar). The Visuals panel opens.
 Click Add.

Click the Box ploticon.
 Drag at least one measure from the Data panel into the Value field well.
 (Optional) Drag a dimension from the Data panel into the Group By field well. Box plots support up to five metrics and one groupby but don't render if duplicate metrics are supplied.
 (Optional) To add drilldown layers, drag at least one more dimension from the Data panel into the Group By field wells. For more information about adding drilldowns, see Adding drilldowns to visual data in Insights.
