A box whisker chart displays the distribution of data into quartiles. The boxes may also have lines extending vertically (whiskers). The lines indicate variability outside the upper and lower quartiles. A point outside the whisker is an outlier point. Box whisker charts are commonly used in statistical analysis.
You can use the BoxWhiskerSeries, the ClusteredBoxWhiskerSeries, and the YPlotArea classes to create a box whisker chart with multiple series as shown in the following image.
For information about creating charts in the Spread Designer or the Chart Designer, refer to Adding a Chart Control or Using the Chart Designer.
Using Code
- Add data for the chart.
- Add the chart.
- Set any additional properties such as whether to show the mean lines.
Example
This example creates a box whisker chart.
