.Net Analytics Controls - Range

The Range chart is designed to plot time series data that consists of multiple observations (called samples in the control) per subgroup. The value plotted is the range between the observations/samples within a subgroup. The control allows for data to be plotted via index, code, datetime, or name. Some of the features of the Range control are discussed below. Other features are listed in the documentation and API:


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.

Split Limits

The control allows for the limits to be split. An example of this can be seen in the chart below. The chart on the left is the Xbar which contains the same data. Split limits are used when a process changes at a particular observation/sample. The limits can be split at an index, code, or datetime.

Run Rules

There are nine rules built into the controls (including the Western Electric rules) and users can build custom rules as well. The first run rule (check to see if a sample is above the UCL, the upper control limit, or below the LCL, the lower control limit) can be seen in the example below. The chart on the left is the Xbar which contains the same data.

Zones

The control allows for zones (A, B, and C) to be shown. The zones represent 1, 2, and 3 sigma deviations from the center line. An example is shown below. The chart on the left is the Xbar which contains the same data.

Statistics

The Range 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 Range control are:

  • Above USL
  • Anderson-Darling
  • Average Squared Deviation
