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.

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...... JG |

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) { } Sierra Chart Support - Engineering Level Your definitive source for support.
