Hello, I have successfully used several drawing tools in a custom study, but DRAWING_DATE_MARKER defeated me: I cannot get it to draw a date marker after many tries. Could you please provide an example. Thank you. |

You would get a better response if you show what you actually tried to do - The code.

Here is the code I use: int drawDateHighlight(SCStudyGraphRef sc, SCDateTime dateTime, float beginValue, float endValue, int& dateHighlightLineNumber) { s_UseTool Tool; Tool.ChartNumber = sc.ChartNumber; if (dateHighlightLineNumber != 0) Tool.LineNumber = dateHighlightLineNumber; // Tool.DrawingType = DRAWING_VERTICALLINE; // Tool.LineStyle = LINESTYLE_DASH; // Tool.LineWidth = 1; Tool.DrawingType = DRAWING_DATE_MARKER; // Tool.UseRelativeVerticalValues = 1; Tool.BeginDateTime = dateTime; Tool.BeginValue = beginValue; Tool.EndValue = endValue; Tool.Color = COLOR_YELLOW; Tool.AddMethod = UTAM_ADD_OR_ADJUST; Tool.AddAsUserDrawnDrawing = 1; sc.UseTool(Tool); return Tool.LineNumber; } I have tried passing the beginValue and endValue in terms of tick values of the interesting bar and I have tried the values with sc.UseRelativeVerticalValues=1. Nothing ever appeared on screen. I ended up using a vertical line (commented code). Any help is appreciated. The documentation at Using Drawing Tools From an Advanced Custom Study says that DRAWING_DATE_MARKER is available but nothing is said about what other parameters must be provided. |

Oh! I cannot make it work either sorry. It is actually returning an error as soon as I use DRAWING_DATE_MARKER SCString MessageText; int test; test = sc.UseTool(Tool); MessageText.Format(" Index: %d, Error Code: %d ", sc.Index, test); sc.AddMessageToLog(MessageText, 0); Since this thread is marked as [Programming Help] SC staff I don't think will look at it. Maybe you could prompt them to have a look at it. |
