    Box-and-Whisker
    In This Topic

    Box-and-Whisker series allows you to display groups of data into the range, quartiles, and median. The name itself suggests that the series depicts data through boxes and whiskers.

    A box is the range showing the quartiles (lower and upper) and the median. Whiskers, on the other hand, are the lines extending vertically from the boxes. These lines indicate the data variability outside the lower and the upper quartiles. In addition, points that lie outside of these lines are known as outliers.

    Box-and-Whisker series is ideal for visualizing statistical distribution or examining multiple sets of data graphically.

    Box-and-Whisker series in FlexChart allows working with different features, as follows:

    The following image displays quartiles, median, and whiskers for the data that compares scores of students in three subjects across different schools.

    The following code uses data regarding scores obtained by students of schools A, B, and C in three subjects. The code illustrates how to implement Box-and-Whisker series in FlexChart.
