stringo:

That's not the point I was making.

It says tester agent logs, it means tester agent logs.

Well first, for the latecomers, you need to specify where and what (preferably in pictures)...

Is it possible to make the object move by dragging smoothly horizontally or vertically?

I want to make a kind of scroll for a graph.

Is it possible to make an object move by dragging smoothly The chart object can be made to move along a horizontal or vertical line?

I want to make a kind of scroll for the graph.

Found a script, tweaked it a bit:

#import "user32.dll"
bool      GetCursorPos(int &Pos[]);
bool      GetWindowRect(int hWnd,int &Pos[]);
#import
//+------------------------------------------------------------------+
//| Script program start function                                    |
//+------------------------------------------------------------------+
void OnStart()
  {
//---
   int p[2];
   int rect[4];
   int hwnd=ChartGetInteger(ChartID(),CHART_WINDOW_HANDLE);
   while(!IsStopped())
     {
      GetWindowRect(hwnd,rect);
      GetCursorPos(p);
      int X=p[0]-rect[0];
      int Y=p[1]-rect[1];
      string c="Глобальные координаты мыши x= "+p[0]+" y= "+p[1]+"\n"+
               "Координаты мыши в окне котировок x= "+X+" y= "+Y;
      Comment(c);
      Sleep(100);
     }
  }
//+------------------------------------------------------------------+

I'll try to use user32.dll to get mouse coordinates to make scrolling smooth, should work.

In general it would be nice to have built in Chart object navigation.

Have you seen the example in the Angle section?

[Oleg Tsarkov]

Rosh:
Did you look at the example in the Binding Angle section ?

Thanks, already found and deleted the message, but you were quicker:)

I have another question, the EA works on OnTimer but the window is updated only with the next tick, can this be dealt with?

The window in the sense of objects on the chart?

ChartRedraw - forcibly redraw the chart (most likely this should help).

Interesting:

ChartRedraw - forcibly redraws the graph (this should probably help).

I put ChartRedraw(0); , the window is exactly zero and the only one, it does not help, the objects are updated only after the next tick, although Print() shows the change of data once per second EventSetTimer(1)

Then, at the very least, more information is needed.

What are the objects? Who creates them and how (for example, objects can be created/changed by an owl or by an indicator)?

And the situation in general is described very vaguely.
