The log indicates that the code runs to place text on the chart but it never appears. sc.AddMessageToLog("=============GETS HERE=============", 0); //TEXT VALUE ON CHART s_UseTool Tool; Tool.Clear(); Tool.Region =0; Tool.ChartNumber = sc.ChartNumber; Tool.DrawingType = DRAWING_STATIONARY_TEXT; Tool.LineNumber = 12348; Tool.BeginDateTime = 38; Tool.BeginValue = 80; Tool.Color = COLOR_YELLOW; Tool.Text ="HELLO W... "; Tool.FontSize = 40; Tool.AddMethod = UTAM_ADD_OR_ADJUST; sc.UseTool(Tool); |

One possibility is the Tool.BeginValue. Is 80, within the screen range? Or, did you intend for it to be a 0 - 100 range percentage.? If the percentage, then you also need this line of code. If UseRelativeVerticalValues is set to 1 or a nonzero value, then BeginValue is a value relative to the Chart Region itself completely independent of the scale used for the graphs in the Chart Region. It is a percentage. Where 1 = 1%. The entire height of the Chart Region is 100%. 0 = The bottom of the Chart Region. 100 = The top of the Chart Region. These values apply to the Chart Region and not the entire height of the chart window unless there is only a single Chart Region displayed. JohnR |

I thought that the drawing type DRAWING_STATIONARY_TEXT didn't need the statement UseRelativeVerticalValues... It seems to be working that way elsewhere...
