Post From: Setting sc.Subgraph[].TextDrawStyleText dynamically

Thank you. I have tested based upon your example as below and I receive the same Index value displayed at the base of every bar, i.e. it is not displaying an incrementing value:


#include "sierrachart.h"

SCDLLName("TextDrawStyleTextTest")

SCSFExport scsf_TemplateFunction1(SCStudyGraphRef sc)
{
  // Set the configuration variables
  
  if (sc.SetDefaults)
  {
    
    
    sc.GraphName = "TextDrawStyleTextTest1";
    sc.GraphRegion = 0;
    sc.AutoLoop = 1; // true

    // During development set this flag to 1, so the DLL can be rebuilt without restarting Sierra Chart. When development is completed, set it to 0 to improve performance.
    sc.FreeDLL = 0;

    sc.Subgraph[0].Name = "TextTest";
    sc.Subgraph[0].DrawStyle = DRAWSTYLE_TEXT;
    
    return;
  }
  
  
  // Data processing
  
  SCString DisplayString;
  DisplayString.Format("%u", sc.Index);
sc.Subgraph[0].TextDrawStyleText = DisplayString;
  sc.Subgraph[0][sc.Index] = sc.Low[sc.Index] - (2 * sc.TickSize);
}


I am aiming to display text that is conditional based upon the bar (or my indicator), i.e.


#include "sierrachart.h"

SCDLLName("TextDrawStyleTextTest")

SCSFExport scsf_TemplateFunction1(SCStudyGraphRef sc)
{
  // Set the configuration variables
  
  if (sc.SetDefaults)
  {
    
    
    sc.GraphName = "TextDrawStyleTextTest1";
    sc.GraphRegion = 0;
    sc.AutoLoop = 1; // true

    // During development set this flag to 1, so the DLL can be rebuilt without restarting Sierra Chart. When development is completed, set it to 0 to improve performance.
    sc.FreeDLL = 0;

    sc.Subgraph[0].Name = "TextTest";
    sc.Subgraph[0].DrawStyle = DRAWSTYLE_TEXT;
    
    return;
  }
  
  
  // Data processing
  
  SCString DisplayString;

  // Display a string based upon the last price in the bar

  if (sc.Close[sc.Index] == sc.Close[sc.Index - 1])
  {
    DisplayString = "Unchanged";
  }
  else if (sc.Close[sc.Index] > sc.Close[sc.Index - 1])
  {
    DisplayString = "Higher";
  }
else
  {
    DisplayString = "Lower";
  }
  sc.Subgraph[0].TextDrawStyleText = DisplayString;
  sc.Subgraph[0][sc.Index] = sc.Low[sc.Index] - (2 * sc.TickSize);
}

however as with the code based upon your example, this repeats a single string for every bar based upon the conditional result of the first bar.

Am I missing something based upon AutoLoop perhaps?
