How to set EndBarsAgo propety of Region?

[fx.practic]

Hello.

In NT7 I make regions this way:

IRegion Up_Zone;

void override OnStartUp()
{
Up_Zone = DrawRegion("Up_Zone", 0, 0, LineUp1, LineUp2, Color.Empty, Color.Blue, 10 );	
}

void override OnBarUpdate()
{
Up_Zone.EndBarsAgo = 0;	
}

This works fast. But, as for as I see - this way is not valid in NT8.

So, how can I do same in NT8 in correct way?

Thank You.

Have you looked at "Draw.RegionHighlightY()" or "Draw.RegionHighlightX()"?

I believe that might do what you are looking for.

Here is the answer:

Up_Zone.EndAnchor.DrawnOnBar   = 0; 
Up_Zone.StartAnchor.DrawnOnBar = CurrentBar;

Hello fx.practic,

The general supported way to move or modify a drawing object is to call the drawing object again with the same tag name. This is so that if there are any internal methods they called / updated when the object is constructed.

For example in NT7:
protected void OnBarUpdate()
{
DrawRegion("Up_Zone", 0, 0, LineUp1, LineUp2, Color.Empty, Color.Blue, 10 );
}

or in NT8:
protected void OnBarUpdate()
{
Draw.Region(this, "Up_Zone", 0, 0, LineUp1, LineUp2, Brushes.Transparent, Brushes.Blue, 10);
}

If you find any odd or undesired behavior, I would recommend using the supported way of modifying a drawing object.

I didn't make measurements on NT8, but on NT7 "my" method work about 5-8 times faster.

Thank You for Your answer.
