I was be able to find out the definition of the SetSampledValue (Page 137 QCSPCChartNetManual.pdf), but I don't know how this function to add a new double array of value into historical point.
I am having a question that how to add a double array of new values into historical point.
(I am using SPCBatchVariableControlChart class base)
Thanks for your advice. |

No, the software is not designed to do modifications like you describe. All sample data needs to be input using ChartData.AddNewSampleRecord method. It may be you need to clear out the chart data and re-enter the corrected values in the proper sequence. Also, unless you are specifically using one of the chart types which allow a variable number of samples per samples sub group (discussed in the manual), all of your sample sub groups must have the same number of samples. Anything other than that will result in bad SPC calculations. |

Actually, I would like to modify historical point. For example, at point 15 has 15 sample values. I would like to add 20 more sample values into the point 15, so total will be 35 sample values for point 15. Does this possible to do?
Thanks for your advice

The only way to add new values into the historical buffers is to use the ChartData.AddNewSampleRecord method, as done in all of our example programs. You should not be trying to sample data to the charts any other way.
