The QCSPCChart SPC Control Chart Tools software is an object oriented toolkit aimed at developers who want to add static and dynamic quality control charts to their workstation and web applications. Typical users are SPC engineers and other quality control professionals creating applications that will be used to monitor critical quality factors in manufacturing, process, and service industries. The toolkit includes templates for the most common SPC control chart types: variable control charts (X-Bar R, X-Bar Sigma, Individual Range, Median Range, EWMA, MA, MAMR, MAMS and CuSum charts), attribute control charts (p-, np-, c-,  u-, and DPMO charts), frequency histograms, probability charts and Pareto diagrams. The software will automatically calculate SPC control limits using historical data for the supported variable control chart and attribute control chart types. Alarms can be generated for standard +3 sigma control limits, or standard SPC rule sets (WECO, Nelson, Juran, Hughes, Gitlow, AAIG, Westgard and Duncan).  It will also calculate process capability ratios (Cp, Cpl, Cpu, Cpk and Cpm) and process performance indices (Pp, Ppl, Ppu and Ppk). Versions available for .Net (VB and C#), WPF (VB and C#), .Windows Apps, Android, Java, Silverlight and JavaScript. Full developer versions for $300 - $450.
