Hi, sorry but I can't make this work to save my life, I am just trying to reference other charts in ASCIL and I can pull from the chart the study is loaded on, but not other charts, and even though I have it set to another chart it shows the studies from the current chart in the drop down list. Please see pic if I am not being clear. Should this code correctly pull from chart 2, study 1, subgraph 1 when loaded on chart 1? SCSFExport scsf_MTFStudyAverageV2(SCStudyInterfaceRef sc) { SCSubgraphRef Average = sc.Subgraph[0]; if (sc.SetDefaults) { sc.GraphName = "MTF Study Average"; sc.FreeDLL = 1; sc.AutoLoop = 1; sc.CalculationPrecedence = LOW_PREC_LEVEL; Average.Name = "Study Average"; Average.DrawStyle = DRAWSTYLE_LINE; Average.LineWidth = 2; Average.PrimaryColor = RGB(0,0,0); sc.Input[0].Name = "Chart Number 1";; sc.Input[0].SetChartNumber(2); sc.Input[1].Name = "Study ID 1"; sc.Input[1].SetStudyID(1); return; } SCGraphData StudyData; sc.GetStudyArraysFromChartUsingID(sc.Input[0].GetChartNumber(), sc.Input[1].GetStudyID(), StudyData); if(StudyData.GetArraySize() == 0) return; SCFloatArrayRef SubgraphArray = StudyData[0]; if(SubgraphArray.GetArraySize() == 0) return; Average[sc.Index] = SubgraphArray[sc.Index]; I have tried code that worked previously and I have tried the current documentation for sc.GetStudyArrayFromChart(), sc.GetStudyArrayFromChartUsingID(), sc.GetStudyArraysFromChart(), and I get the same results regardless of how I do it. Thank you for any help.

You are not using the correct input type. You need to use the Study input type which combines both a Chart and a Study as one input. You need to use this: https://www.sierrachart.com/index.php?l=doc/doc_ACSIL_Members_scInputs.html#scInputSetChartStudyValues Sierra Chart Support - Engineering Level Your definitive source for support.

Hi, revised the code as indicated, but I am still having same exact problem. I know I am missing something obvious, I just can't figure it. Sorry, thanks again for any help. #include "sierrachart.h" SCDLLName("MTFStudyAverageV2") /==========================================================================/ SCSFExport scsf_MTFStudyAverageV2(SCStudyInterfaceRef sc) { SCSubgraphRef Average = sc.Subgraph[0]; if (sc.SetDefaults) { sc.GraphName = "MTF Study Average"; sc.FreeDLL = 1; sc.AutoLoop = 1; sc.CalculationPrecedence = LOW_PREC_LEVEL; Average.Name = "Study Average"; Average.DrawStyle = DRAWSTYLE_LINE; Average.LineWidth = 2; Average.PrimaryColor = RGB(0,0,0); //sc.Input[0].Name = "Chart Number 1";; //sc.Input[0].SetInt(2); //sc.Input[1].Name = "Study ID 1"; //sc.Input[1].SetInt(1); sc.Input[0].SetChartStudyValues(2, 1); return; } int ChartNumber = sc.Input[0].GetChartNumber(); int StudyID = sc.Input[0].GetStudyID(); SCGraphData StudyData; sc.GetStudyArraysFromChartUsingID(ChartNumber, StudyID, StudyData); if(StudyData.GetArraySize() == 0) return; SCFloatArrayRef SubgraphArray = StudyData[0]; if(SubgraphArray.GetArraySize() == 0) return; Average[sc.Index] = SubgraphArray[sc.Index]; } Date Time Of Last Edit: 2014-02-04 22:47:24

A quick look at the code shows that it does look correct. For an example, refer to /ACS_Source/studies7.cpp/scsf_ReferenceDataFromAnotherChart Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Ok, so I happened to scroll way back on Chart 1 and I can see what is happening now, it is plotting the ADX from Chart 2 bar for bar on Chart 1, it is not matching up the time index and stretching it out, see pic. Should I be doing something with the indexing, or something else, or is this hinky behavior? I looked at the example you referred to and it shows getting the other charts index values, but not using them for purposes of the subgraph plot. Thanks again.

Bump :-) I know I am doing something stupid, but I looked at this again with fresh eyes and still don't see it. Any input would be greatly appreciated. Thanks in advance for any help.
