Control Charts to support manufacturing quality control: X-bar R + I-MR Chart
We would like to be able to generate control charts to show measurements of some property of a product (e.g. mass, thickness, voltage, ppm of a chemical, etc.) over time and also overlay statistical measures line charts including the mean of the sample, ±3σ, UCL (Upper Control Limit - an upper threshold specification value), LCL (Lower Control Limit - a lower threshold specification value), and highlighting data points that may be out of control based on the 7 Wester Electric rules (https://en.wikipedia.org/wiki/WesternElectricrules). For additional information check out http://asq.org/learn-about-quality/data-collection-analysis-tools/overview/control-chart.html.
Hi @Rahul. Yes, it should be possible to implement all SPC Rules. The only example I have is the one below (where only Rule 1 is added): https://jsfiddle.net/BlackLabel/y74rat0z/

Hi Pawel - It is possible to implement all SPC trend Rules in high charts for SPC charts ? If yes then do you have example on this ?
Just in case, it's already possible to create this chart, but we need to calculate all variables on the chart, for example: https://jsfiddle.net/BlackLabel/y74rat0z/ (only Rule 1 applied on a chart).
