As per title, sc.IndexOfFirstVisibleBar and sc.IndexofLastVisibleBar are not updating on chart scrolling even with sc.UpdateAlways = 1. Example test program that demonstrates this: #include "sierrachart.h" SCDLLName("VisibleBarTest") /*==========================================================================*/ SCSFExport scsf_VisibleBarTest(SCStudyInterfaceRef sc) { SCSubgraphRef Subgraph_FirstBarNumber = sc.Subgraph[0]; SCSubgraphRef Subgraph_LastBarNumber = sc.Subgraph[1]; if (sc.SetDefaults) { // Set the configuration and defaults sc.GraphName = "Visible Bar Test"; sc.ValueFormat = 1; sc.AutoLoop = true; Subgraph_FirstBarNumber.Name = "First Bar"; Subgraph_FirstBarNumber.DrawStyle = DRAWSTYLE_SUBGRAPH_NAME_AND_VALUE_LABELS_ONLY; Subgraph_FirstBarNumber.PrimaryColor = COLOR_GREEN; Subgraph_LastBarNumber.Name = "First Bar"; Subgraph_LastBarNumber.DrawStyle = DRAWSTYLE_SUBGRAPH_NAME_AND_VALUE_LABELS_ONLY; Subgraph_LastBarNumber.PrimaryColor = COLOR_GREEN; sc.UpdateAlways = 1; //for visible bars return; } Subgraph_FirstBarNumber[sc.Index] = sc.IndexOfFirstVisibleBar; Subgraph_LastBarNumber[sc.Index] = sc.IndexOfLastVisibleBar; } /*==========================================================================*/ |
