| 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;
