I have the following JSON configuration:

It seems that if USL or LSL are missing, UCL1/UCL2 still render even if there is the text and line are disabled.

Am I missing something?

Additional control limits should be added in a specific order. The standard +- 3,2,1 sigma limits must be first. The +- 3 sigma limits are added by default. The 123SigmaControlLimits block should come next and it adds the +-2 and +-1 sigma limits. After that you can add custom limits. Specification limits, if used, should come last. So in your JSON, move the 123SigmaControlLimits block above the AddControlRules block.

"ControlLimits": {
"123SigmaControlLimits": {
"Target": 0,
"UCL3Value": 0,
"LCL3Value": 0,
"AlarmTest12": false,
"EnableAlarmLine": false,
"EnableAlarmLineText": false,
"EnableAlarmChecking": false
},
"AddControlRules": [{
"RuleSet": "CUSTOM_TEMPLATE_BASED_RULE",
"RuleNumber": 2,
"EnableAlarmLine": false,
"EnableAlarmChecking": true,
"EnableAlarmLineText": "",
"LimitValue": 0,
"M": 6,
"N": 6,
"SigmaLevel": 0
}, {
"RuleSet": "CUSTOM_TEMPLATE_BASED_RULE",
"RuleNumber": 1,
"EnableAlarmLine": false,
"EnableAlarmChecking": true,
"EnableAlarmLineText": "",
"LimitValue": 0,
"M": 6,
"N": 6,
"SigmaLevel": 0
}, {
"RuleSet": "CUSTOM_TEMPLATE_BASED_RULE",
"RuleNumber": 2,
"EnableAlarmLine": false,
"EnableAlarmChecking": true,
"EnableAlarmLineText": "",
"LimitValue": 0,
"M": 1,
"N": 1,
"SigmaLevel": 3
}],

.
.
.


Also, one minor, unrelated, point. In your sample data, do not specify all values in a sample interval with the same value. That means the sample interval has zero range, and that violates the central tenent of SPC charts, which is that sample data approimates a normal distribution. Data with no range does not work well in the control limit calculations. Give at least one sample for each interval a different value.

"SampleValues": [312, 312, 315, 312, 312],


in order to introduce some variation.
