We want to allow users to calculate control limits on a sub-set of data. After the control calculates the control limits, the values will be stored in a table. The next time the chart is run, the control limits will not be calculated and the stored values will be used.

I am unable to find how can I get calculated control limits out of the chart to save. I tried the pushGetJSONOverallStatistics but I do not see the control limits in the results.

Sorry, but the ability to retrieve values programmatically from the JavaScript code is very limited, because most all of the interaction with the chart is through one way JSON scripting. There is no special function for retrieving control limit values. The only thing we can suggest is to record the limit values manually and then use those values to set manual, rather than auto-calculated limits.

Can we sponser this feature to be added to the JavaScript code? If yes, can you email me a potential timeframe and cost to cmurphy@iqs.com. Thank You.

Yes, that is always an option. Please think about if you have other return values you would like to see, since doing them all at once is by far the most cast effective means. These might include other limit values (+-2 sigma, +-1 sigma), mean, Process Performance (Ppk) and Process Capability Indices(Cpk)) values, for both the Primary and Secondary charts where applicable. Send your response to support@quinn-curtis.com. We can investigate and back to you in a couple of days.
