.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:
