[Programming Help] - sc.UseTool and Line not drawing properly with 1-150 X axis values

See attached images. with 75 as anchor 2 of line properties, line ends at 50% or halfway of the window. with 150 as anchor 2 of line properties, line extends only to last bar and not the right side of the window. The real use case here is to use sc.UseTool for Tool.DrawingType = DRAWING_LINE; to accomplish the same thing (line all the way across). When drawn from code, the same behavior is observed. Please advise, thanks. |

From my observation that happens only if UseRelativeVerticalValues is disabled. By setting it to 1 the anchor of 150 goes to the end of the chart. But unfortunately I believe that makes it not possible to draw a line at absolute values like a price and use relative horizontal values at the same time properly. Thanks in advance for your support. |

the docs have a note about drawing into the fill space with EndDateTime or EndIndex Using Drawing Tools From an Advanced Custom Study: s_UseTool::EndDateTime |

you might also try a different drawing type if you're just looking for a full width price level or similar Using Drawing Tools From an Advanced Custom Study: s_UseTool::DrawingType Date Time Of Last Edit: 2024-08-31 18:06:41

They do, but that is not relevant if you are using relative positioning. The purpose being to position drawings in fixed location via coordinate system, not tied to a bar index or real datetime. Seems something is broken. Or maybe some drawing tools don't play nice with relative positioning? Date Time Of Last Edit: 2024-08-31 18:29:23

We do not see any problem with this. There definitely is nothing in the code, which positions, a Chart Drawing with consideration to coordinates of chart bars, when using relative horizontal positioning (0 to 150), and there is also a high-resolution version of this, available. Positioning is relative to the Chart Region itself. Here is an example of the Symbol Display: https://www.sierrachart.com/image.php?Image=1725144997418.png Make sure you are running an up-to-date version of Sierra Chart.

Huh? You posted a reply with text, not a line. Question was about making a line extend to end of the chart not just the last bar.

i think the issue is you're trying to combine absolute y with relative x, which doesn't seem possible

using the previously linked EndIndex or extended DrawingType does what you want, i think.. #include "sierrachart.h"
SCDLLName("fill space line") SCSFExport scsf_fill_space_line(SCStudyInterfaceRef sc) { if (sc.SetDefaults) { sc.AutoLoop = 0; sc.DisplayStudyName = 0; sc.GraphName = "fill space line"; sc.GraphRegion = 0; sc.UpdateAlways = 1; return; } double last_price = sc.GetLastPriceForTrading(); double price_begin = last_price - (last_price * 0.0025); double price_end = last_price + (last_price * 0.0025); s_UseTool tool; tool.Clear(); tool.AddMethod = UTAM_ADD_OR_ADJUST; tool.BeginIndex = sc.IndexOfFirstVisibleBar; tool.BeginValue = (float) price_begin; tool.Color = 0xff0080; tool.DrawingType = DRAWING_LINE; tool.EndIndex = sc.IndexOfLastVisibleBar + (int) sc.NumFillSpaceBars; tool.EndValue = (float) price_end; tool.LineWidth = 10; int& line = sc.GetPersistentIntFast(0); if (line != 0) tool.LineNumber = line; sc.UseTool(tool); line = tool.LineNumber; } Date Time Of Last Edit: 2024-09-01 02:15:45
