Accessing sc.Subgraph[].Arrays[][] from a different chart or study

SC,

The documentation indicates that a subgraph's extra arrays are for internal use, but I would like to access them from a 2nd, different study on a different chart, coded in another DLL. So study 2 (scsf_study2) on chart 2 wants to read subgraph extra arrays internal to study 1 (scsf_study1), chart 1.

Does   sc.GetStudyArraysFromChart( chartNum, studyID, graphData ) return pointers to the subgraphs themselves (BaseData[x] ), without performing a physical copy from source to destination study?

The following code compiles, altho I haven't tested it. Assuming this is pointer-based, then the code should work and be much more expedient.

    sc.GetStudyArraysFromChart( chartNum, studyID, sgArrays15secAgent ) ;
    SCFloatArrayRef StudyArray = sgArrays15secAgent[0];  
    
    SCSubgraphRef sgRef = (SCSubgraphRef) sgArrays15secAgent[2];  
    SCFloatArrayRef myArray = sgRef.Arrays[0];

thx in advance,

JG

This will not work properly. We would have to add a function to be able to get the extra study arrays from another chart or study. We will see about that.

This function will be added to the next release:
sc. GetStudyExtraArrayFromChartUsingID(int ChartNumber, int StudyID, int SubgraphIndex, int ExtraArrayIndex, SCFloatArrayRef ExtraArrayRef);

SC,

Thanks - to echo what others have said: Excellent customer support, and IMHO, one of the best customer/trader experiences on the internet.

Esp. for C++ traders......

This is now released. Although it has not yet been tested. Please test and let us know.

Tried this with 2 different Arrays; no problems found.

thx again for the quick turnaround

Little doubt that Sierrachart's support is not the fastest and high level. Kudos!

That, however, doesn't make me much of a programmer. Could somebody use sc.GetStudyExtraArrayFromChartUsingID in a sentence for me [provide example code]? I have version 997 and can't even get things to build. I don't understand the use of ExtraArrayRef. I suppose that SCFloatArrayRef would refer to a subgraph where I was placing the data gotten from another chart, no?

I dl'd the prerelease and it will build if I don't use the ExtraArrayRef term:

SCFloatArrayRef ReceivedDataFromOtherChart =sc.Subgraph[5];
sc.GetStudyExtraArrayFromChartUsingID(1, 1, 0, 0, ReceivedDataFromOtherChart );

I guess I can make sense out of it...

You need to update to the latest prerelease. Here is a very simple example:

  
  SCFloatArray ExtraArrayFromChart ;
  sc.GetStudyExtraArrayFromChartUsingID(1, 1, 0, 0, ExtraArrayFromChart);
  if (ExtraArrayFromChart.GetArraySize()>0)
  {

  }
