Setting sc.Subgraph[].TextDrawStyleText dynamically

Is it possible to set sc.Subgraph[].TextDrawStyleText dynamically within a custom study so that depending upon the value of the Subgraph, a different text string is displayed? My attempts so far are failing and only the first value that TextDrawStyleText is set to is displayed, even if the code later changes the vale of TextDrawStyleText. As an aside, it would be great to have a DrawStyle similar to CustomValueAtY that could display a variable text value. |

Yes you definitely can. If this is not working properly, then it is because there is a problem in your code. We verified this can be changed at any time just by assigning a new text string. It is simple as that. Here is the test we put together: SCString NumberString;
NumberString.Format("%u", sc.Index); SecondSubgraph.TextDrawStyleText = NumberString; SecondSubgraph[sc.Index] = sc.Close[sc.Index]; Sierra Chart Support - Engineering Level Your definitive source for support.

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? Date Time Of Last Edit: 2016-12-11 16:37:08

All displayed elements of a particular Subgraph using the Text Draw Style will display the same string value.
