.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
