    Box Whisker Charts
    In This Topic

    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

    1. Add data for the chart.
    2. Add the chart.
    3. Set any additional properties such as whether to show the mean lines.

    Example

    This example creates a box whisker chart.
