.Net Analytics Controls - Q-Chart
The Q-chart is designed to plot transformed statistics from the individuals
chart. Each sample has its own control limit calculations that are based upon
itself and the previous samples. 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.
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:
Statistics
The Q-chart 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 Q-chart control are:
- Average Squared Deviation
- Count
- Kurtosis
- Maximum
- Mean
- Median
- Minimum
- Range
- RMS Deviation
- Sigma
- Skewness
- Standard Deviation
- Variance
