Box Plot

The view can be accessed either via the “Open view” action on the executed node or on KNIME Hub.
In the node configuration, you can enable certain controls, which are then available in the view. This includes the ability to choose different dimension columns and a condition column or the possibility to set a title.
The configuration also offers a preview of the view, which should help to get the box plot in the desired shape quickly.

A box plot is constructed in the following way: The box itself goes from the lower quartile (Q1) to the upper quartile (Q3). The median is drawn as a horizontal bar inside the box. The distance between Q1 and Q3 is called the interquartile range (IQR).
Above and below the box are the so-called whiskers. They are drawn at the minimum and the maximum value as horizontal bars and are connected with the box with a line. The whiskers never exceed 1.5 * IQR. This means if there are some data points which exceed either Q1 - (1.5 * IQR) or Q3 + (1.5 * IQR) than the whiskers are drawn at exactly these ranges and the data points are drawn separately as outliers.

Since missing values as well as NaN (not a number) cannot be displayed in the view, they will be omitted.
