17.2.2 Creating Box ChartsCreate-Box-Chart
The box plot, which is also called a box and whisker plot or box chart, is a graphical representation of key values from summary statistics.
To create a box chart:
- Highlight one or more Y worksheet columns (or a range from one or more Y columns).
- Select Plot: Statistical: Box Chart.
Each Y column of data is represented as a separate box. The column names or labels supply the X axis tick labels. By default, the box is determined by the 25th and 75th percentiles. The whiskers are determined by the 5th and 95th percentiles. Additional values can be represented in Origin's box chart, including the minimum, median, mean, maximum, the 1st and 5th percentiles, and 95th and 99th percentiles.
You can also create a grouped box chart, from either indexed data or raw data.
To customize the Box Chart display:
- Double-click on the box chart.
or
- Right-click and select Plot Details.
Both actions open the Plot Details dialog box with the box chart data plot icon active on the left side of the dialog box. The box chart controls are available on tabs on the right side of the dialog box.

Box Chart Examples
Box chart has been largely improved in the previous versions and now it has many variations. Several typical examples are displayed below. All examples were created from the data in BoxChartExample.ogw, in the <Origin EXE folder>\Samples\Graphing folder. The table references datasets (columns) in the BoxChartExample worksheet and menu entry to create the graph, and also lists key settings and main customizations made in the Plot Details dialog box.
