Okay, I've made a bunch of changes to utilize settings' inputs because I realized I needed to save the value. My input is updated by the right-click menu event, but the subgraph is not drawn in less I open up the settings for the study and click okay. Any ideas?


#include "sierrachart.h"

SCDLLName("My Studies")

SCSFExport scsf_BalanceZones(SCStudyInterfaceRef sc)
{
  SCString MessageText;
  
  SCSubgraphRef Subgraph_BalanceZoneTop = sc.Subgraph[0];
  SCSubgraphRef Subgraph_BalanceZoneBottom = sc.Subgraph[1];

  SCInputRef BalanceHigh = sc.Input[0];
  SCInputRef BalanceLow = sc.Input[1];

if (sc.SetDefaults)
{
    sc.GraphName = "Balance Zones";
    sc.StudyDescription = "";
    sc.DrawZeros = 0;
    sc.GraphRegion = 0;
    sc.ValueFormat = 3;
    sc.AutoLoop = 1;

    Subgraph_BalanceZoneTop.Name = "Balance zone top";
    Subgraph_BalanceZoneBottom.Name = "Balnce zone bottom";

    BalanceHigh.Name = "Balance high";
    BalanceHigh.SetFloat(0);

    BalanceLow.Name = "Balance low";
    BalanceLow.SetFloat(0);

return;
}

  int& r_MenuID = sc.GetPersistentInt(1);

  if (sc.LastCallToFunction)
  {
    sc.RemoveACSChartShortcutMenuItem(sc.ChartNumber, r_MenuID);

    return;
  }
  
  if (sc.UpdateStartIndex == 0)
  {
    if (r_MenuID <= 0)
    {
      r_MenuID = sc.AddACSChartShortcutMenuItem(sc.ChartNumber, "Draw balance zones");
    }

    return;
  }
  
  s_UseTool ChartDrawing;

  if (sc.MenuEventID != 0 && sc.MenuEventID == r_MenuID)
  {
    int selectedLineNumber = sc.GetLineNumberOfSelectedUserDrawnDrawing();    
    
    sc.GetUserDrawnDrawingByLineNumber(0, selectedLineNumber, ChartDrawing);

    BalanceHigh.SetFloat(ChartDrawing.BeginValue);
    BalanceLow.SetFloat(ChartDrawing.EndValue);
  }

  float BalanceHighVal = BalanceHigh.GetFloat();
  float BalanceLowVal = BalanceLow.GetFloat();
  
  Subgraph_BalanceZoneTop[sc.Index] = BalanceHighVal;
  Subgraph_BalanceZoneBottom[sc.Index] = BalanceLowVal;
}
