I am trying to access the first subgraph Bar Numbering on the 2nd chart in the chart book. SCFloatArray Bars; sc.GetStudyArrayFromChart(2, 1, 0, Bars); However the array Bars ends up empty instead of having the bar count so I'm wondering what I am doing wrong? Thanks |

You really should use this Study Input to control all of the parameters properly: https://www.sierrachart.com/index.php?page=doc/doc_ACSIL_Members_scInputs.html#scInputGetChartStudySubgraphValues Sierra Chart Support - Engineering Level Your definitive source for support.

I have copied the example in the link into my code so it now looks like this: SCInputRef StudySubgraphReference = sc.Input[0]; if (sc.SetDefaults) { sc.GraphName = "Automated VWAP Trader"; sc.FreeDLL = 1; sc.AutoLoop = 1; sc.AllowMultipleEntriesInSameDirection = 0; sc.CalculationPrecedence = LOW_PREC_LEVEL; StudySubgraphReference.Name = "Study And Subgraph To Display"; StudySubgraphReference.SetChartStudySubgraphValues(2, 1, 0); return; } SCFloatArray StudyReference; sc.GetStudyArrayFromChartUsingID(StudySubgraphReference.GetChartStudySubgraphValues(), StudyReference); But the StudyReference array is still empty and on the chart itself it shows: "Name of my study" (#0.ID0.SG1) which I believe means it is referencing the chart at #0, the study at 0 and the subgraph of that study at 1 but in the code above I am trying to set it up to reference the chart at #2 the study at 1 and the subgraph of that study at 0. I am wondering where my mistake is in my code. Thanks |

Go to the Study Inputs for this study. How do you have the 3 controls set for the "Study And Subgraph To Display" Input? Could you attach a screenshot.

The Input Values were incorrectly set so I've changed them to the correct values you see in the picture (Note: The chart I am attempting to reference has changed over night from #2 to #1). In the bottom right my message log is showing that the array receiving the subgraph data is no longer empty. It holds 2954 elements, my main chart's current index is 27364, the "nearest index" (found with sc.GetNearestMatchForDateTimeIndex(1, sc.Index) was 2953 which all appears to be correct however all the values in the array appear to be 0.

We do not provide programming help.

Although we did check to make sure that the Bar Numbering study does fill Subgraph at index 0 with the bar number values.

Another thing to consider is study calculation precedence/order: https://www.sierrachart.com/index.php?page=doc/doc_ChartStudies.html#StudyCalculationPrecedence Sierra Chart Support - Engineering Level Your definitive source for support.
