The 'five-number summary' principle is used to plot data on the box and whisker charts. This principle helps to provide a statistical summary for a given set of numbers. It gives information about the range (minimum and maximum numbers), the center (median), and the spread (upper and lower quartiles) for the set of values provided.

FusionCharts Suite XT allows you to customize the five summary numbers and their deviations plotted on a box and a whisker chart according to your requirement.

In this section, you will be shown how you can:

• Show/hide the five summary numbers

• Customize the median

• Customize the upper and lower quartiles (Q1 and Q3)

• Customizing the minimum and maximum numbers (lower and upper whiskers)

Showing/Hiding the Five Summary Numbers

A box and whisker chart with three of the five summary numbers - the minimum and maximum numbers and the median - shown looks like this:

Given below is a brief description of the attributes used to show/hide the five summary numbers:

The data structure needed to render the above chart is given below:

• JSON
• XML

To selectively show the summary numbers on the chart. To do this, you will need to set the showValues attribute to 1, set the required attributes to the value (0 or 1) that will show them, set the remaining attributes to the value (0 or 1) that will hide them. For example, if you want to show only the minimum values, use the code snippet shown below:

{
    "chart": {
        "caption": "Visits to a Website",
        "subcaption": "In three years",
        "showQ1Values": "0",
        "showQ3Values": "0",
        "showMedianValues": "0",
        "showMinValues": "1",
        "showMaxValues": "1"
    }
}

You can also configure the box and whisker chart to show all five summary numbers at once. To do this you can use the code snippet shown below:

{
    "chart": {
        "caption": "Visits to a Website",
        "subcaption": "In three years",
        "showQ1values": "1",
        "showQ3values": "1",
        "showMedianValues": "1",
        "showMinValues": "1",
        "showMaxValues": "1"
    }
}

Customizing the Median (Q2)

The median for a set of numbers is represented by a line at the center of the box plot. The median acts as the separator between the upper and lower quartile boxes.

Given below is a brief description of the attributes used to customize the median:

All these attributes can be used with the chart, dataset, and the data objects, depending on the requirement.

Customizing the Upper and Lower Quartiles (Q1 and Q3)

The quartiles of a set of data are spread as two boxes, separated by the median. The roof of the upper quartile box represents the exact value of the upper quartile (Q3) . The base of the lower quartile box represents the exact value of the lower quartile (Q1).

Given below is a brief description of the attributes used to customize the quartile points and the boxes.

Customizing the Minimum and Maximum Numbers (Lower and Upper Whiskers)

The chart displays the biggest number of a set of values as the upper whisker and the smallest number of the set as the lower whisker.

Given below is a brief description of the attributes used to customize the whiskers:

There! You have now seen how you can customize how the five summary numbers are rendered on the box and whisker chart.
