.Net Analytics Controls - Histogram

The Histogram chart is designed to plot the frequency of observations. Some of the features of the Histogram control are discussed below. Other features are listed in the documentation and API:


Normal Curve

The normal curve for the data may be overlaid on the histgram cells/bins. An example is shown below. The chart on the left is an Individuals and that data is used in the Histogram on the right.

Multiple Series

Multiple series may be added to the chart. The series can be shown together, as seen in the example below, or series can have their visiblily turned off so that only one series is shown at a time.

Statistics

The Histogram control supports a number of statistics. These can be retrieved at any point programmatically, or they can be shown in the statistics box. If you require a statistic that is not in the control, you may contact our Support department, and we can work with you in adding the statistic. The statistics that are currently supported by the Histogram control are:

  • Average Squared Deviation
  • Count
  • Kurtosis
  • Maximum
  • Mean
  • Median
  • Minimum
  • Range
  • RMS Deviation
  • Skewness
  • Standard Deviation
  • Variance
