Ackin, thank for the reply, but the code you send me is not what im looking for. I was able set a different STUDY by changing the code


" GridStart.SetFloat(7000.0f);" (ackin, this is used for manual inputs)



with "GridStart.SetStudySubgraphValues(0,0);" (which gives the option to pick a studyid and the studyid subgragh from the current chart).


my only problem is that i'm not see the values from the ref. studyid and subgraphid. I belive the code I need to change is in the data processing.

"float GridStartVal = GridStart.GetFloat()-GridSpacingVal;" (this is what I need to change)

WITH SAME THING LIKE : I just keep getting error.

// Do data processing

  //This will return sc.UpdateStartIndex or an earlier index if this study is calculated after a study which calculated at an earlier index and supports setting that earlier index.
  int ActualStartIndex = sc.GetCalculationStartIndexForStudy();

  // Get the array for the specified Input Data from the specified studies
  SCFloatArray Study1Array;
  sc.GetStudyArrayUsingID(Input_StudySubgraphReference.GetStudyID(), Input_StudySubgraphReference.GetSubgraphIndex(), Study1Array);

  for (int BarIndex = ActualStartIndex; BarIndex < sc.ArraySize; BarIndex++)
  {
    Subgraph_StudySubgraphReference[BarIndex] = Study1Array[BarIndex];
  }

  sc.EarliestUpdateSubgraphDataArrayIndex = ActualStartIndex;
}




Ackin, or any one please help Thanks again.
