The boxplot is a simple box and whiskers and allows to compare easily across series. Boxplot summarizes a sample data using 25th, 50th and 75th percentiles. These percentiles are also known as the lower quartile, median and upper quartile.The value is plotted on the vertical axis and grouped by the series on the horizontal axis. The actual data values can be exported by right-clicking into the plot and selecting View Values or Save all Curves. To switch ON/OFF the boxplot in the plot area use the boxes available in the plot control area.
