I've studied this code very carefully, but can't figure out why this is happening

#include <Graphics\Graphic.mqh> 

void OnStart()
{
  const string Name = __FILE__;
  const double X[] = {1, 2};
  
  CGraphic Graphic; 

  if (ObjectFind(0, Name) < 0) 
    Graphic.Create(0, Name, 0, 0, 0, 780, 380); 
  else 
    Graphic.Attach(0, Name); 

  ObjectSetInteger(0, Name, OBJPROP_XOFFSET, 0);

  Graphic.CurveAdd(X, CURVE_HISTOGRAM).HistogramWidth(6);
  
  Graphic.CurvePlotAll(); 
  Graphic.Update();  

  Sleep(1000);
  ObjectSetInteger(0, Name, OBJPROP_XOFFSET, 1); // Объект исчезает с экрана
}

Is this a bug in the custom resource or am I doing something wrong?

The script finishes and removes the graphic (you can put Sleep() at the very end to check).

This is not the case.

It wasn't.

Yes, that's right, I also had Destroy() called.

Bug

void OnStart()
{
  int Property = CHART_SHOW; // Если указать тип ENUM_CHART_PROPERTY_INTEGER, то ошибка исчезает
  
  Print(ChartGetInteger(0, Property)); // 'ChartGetInteger' - no one of the overloads can be applied to the function call
}

• CHART_WINDOW_IS_VISIBLE–определяет видимость подокна.

  //+------------------------------------------------------------------+
  //| Функция определяет, является ли данное окно или подокно графика  |
  //| видимым.                                                         |

  bool ChartWindowsIsVisible(bool &result,const long chart_ID=0,const int sub_window=0)
    {
  //--- подготовим переменную для получения значения свойства
     long value;
  //--- сбросим значение ошибки
     ResetLastError();
  //--- получим значение свойства
     if(!ChartGetInteger(chart_ID,CHART_WINDOW_IS_VISIBLE,sub_window,value))
       {
        //--- выведем сообщение об ошибке в журнал "Эксперты"
        Print(__FUNCTION__+", Error Code = ",GetLastError());
        return(false);
       }
  //--- запомним в переменную значение свойства графика
     result=value;
  //--- успешное выполнение
     return(true);
    }

How to make a subwindow invisible and the main subwindow visible?

Explain how the CHART_WINDOW_IS_VISIBLE property(read-only) can be applied?

Hello! What is the metatrader glitch on the eurodollar chart? A daily candle for Sunday 9.10.2011 appeared, on the hour chart there is only one hour 23:00 for that date. This is probably due to the change of clocks to winter time. How to fix it? There was no such candle before.

Bug

More likely a mistake in the documentation

In fact, property_id has always been ENUM_CHART_PROPERTY_INTEGER

Exactly!
