Silverlight Analytics Controls - Pareto

The Pareto chart shows groups of observations/samples and orders those groups in descending order. This allows a user to quickly see which groups are the most important. Three of the features of the Histogram control are discussed below. Other features are listed in the documentation and API:


Displaying Frequencies

The control allows for USL and LSL limits to be set for a series. These limits are used when calculating certain statistics, and the control contains the same statistics as the time series controls (Individuals, Moving Range, Xbar, Range, Standard Deviation...). In the example below, you can add random observations/samples to a randomly chosen group to see how the frequency distribution changes.
