See attached .js and .html to duplicate.

Using the pushGetJSONOverallStatistics(), calculated control limits are retrieved and stored. We then display these stored limits when the chart is displayed.

In the attached .js file, you can see where I am setting the control limits as:
"ControlLimits": {
        "DefaultLimits": [
          true,
          true
        ],
        "Target": {
          "EnableAlarmLine": true,
          "EnableAlarmChecking": true,
		  "LimitValue": 3.225,
		  "DisplayString": "Target"
        },
        "LCL3": {
          "LimitValue": 0.8548125074163435,
          "DisplayString": "LCL"
        },
        "UCL3": {
          "LimitValue": 5.595187492583657,
          "DisplayString": "UCL"
        }
      }


However, when the chart is displayed, the control limits appear as 14,10, 6.

A quick look at your example and I see that you are both setting the control limits, AND calling for Variable Sample Size Limit calculation because you are using the "PERCENT_DEFECTIVE_PARTS_CHART_VSS" chart type. You can't have both. The Variable Sample Size Limit Calculation, which takes place at every sample interval automatically, would override any limits you initially set. So change it to PERCENT_DEFECTIVE_PARTS_CHART, and DO NOT set the "SampleSubgroupSize_VSS" with every sample interval, and check the results.

Thank You. The chart type was the problem and the chart properly reflected the control limit values after I changed it to PERCENT_DEFECTIVE_PARTS_CHART.
