Box and whisker chart how to#

There are many different approaches and opinions on how to summarize statistical data. ''' Private _dataHelper As DataSource = New DataSource().Instance Statistical charts, which include Histogram, Pareto and Box and Whisker, help summarize and add visual meaning to key characteristics of data, including range, distribution, mean and median. ''' Method for creating data for StatisticalChart If (isFahrenheit) temp.HighTemp = temp.HighTemp * 1.8 + 32 ''' Method for initializing StatisticalChartĭim data As List( Of CityDataItem) = GetTemperatureData( New String() įor ( int i = 0 i 8) ? rnd.Next(100, 150) : rnd.Next(150, 200) You also need to set up the chart by setting the ChartType property and other required properties. Set up the data source through the DataSource property and configure the X and Y axes by setting the BindingX and Binding property.

Box and whisker chart series#

To create a WinForms box-and-whisker chart through code, the first step after initializing the control is to clear the default series and add a new series using the Add method. FlexChart also provides options to specify whether to display outliers, inner points, mean line and mean marks through ShowOutliers, ShowInnerPoints, ShowMeanLine and ShowMeanMarks properties respectively. This property accepts the values from QuartileCalculation enumeration. Apart from other series related properties, this class provides properties specific to Box-and-Whisker series such as the QuartileCalculation property, which lets you specify whether to include the median in quartile calculation or not. In FlexChart, Box-and-Whisker can be implemented using the BoxWhisker class which represents a Box-and-Whisker series. For instance, you can easily display the variation in monthly temperature of two cities.

These charts are useful for comparing distributions between many groups or data sets. Any point outside the whiskers is said to be an outlier.

As the name suggests, these values are represented using boxes and whiskers where boxes show the range of quartiles (lower quartile, upper quartile and median) while whiskers indicate the variability outside the upper and lower quartiles. Box-and-Whisker charts are the statistical charts that display the distribution of numerical data through quartiles, means and outliers.
