there any way to get data cp, cpk, sigma, etc in array? I view them independently and not only in graphics or tables it generates. |

The estimated process mean is the same as the target value of the primary chart. These values only make sense after the autoCalculateControlLimits method is called. You can retrieve the UCL and LCL in a similar fashion. The estimated process sigma can be calculated as the (ucl - processMean) / 3;
double meanValue = this.getPrimaryChart().getControlLimitData(SPCChartObjects.SPC_CONTROL_TARGET).getLimitValue();
double ucl = this.getPrimaryChart().getControlLimitData(SPCChartObjects.SPC_UPPER_CONTROL_LIMIT).getLimitValue();
double lcl = this.getPrimaryChart().getControlLimitData(SPCChartObjects.SPC_LOWER_CONTROL_LIMIT).getLimitValue();
double sigmaValue = (ucl - meanValue)/3;

thank you very much, I have another question, processmean processsigma and always returns the values of 1 and 10, I'm doing something wrong?, did as you indicated to me, hehe.
and I have another question, as I can get the values of USL and LSL, the graphics and also require use in the array
forgive my English, I do not speak very well |
