NT8: Extending a rectangle in Ninjascript

[svrz]

Greetings

My intent is to extend a rectangle that has been created via Ninjascript under certain conditions. The following code does not work:

Rect rect = Draw.Rectangle(this, tag, false, 2,
High[2], 0, Low[2], Brushes.Black,
Brushes.Gray, 1);
...
...
...

rect.EndAnchor.BarsAgo = 0;

The alternative is to just create another rectangle with the same tag as the current one. This is a highly inefficient way of achieving this goal.

Please advise.

Thanks in advance.

Hello svrz,

Thank you for the question.

The suggestion in this case would be to call the Draw method again to update the object with the same tag, this is the normal way to update a drawing object. If you are seeing performance impacts due to using many objects, it is generally suggested to instead use OnRender to do the drawing.

I look forward to being of further assistance.

Thank you, Jesse. This is a simple drawing operation hence there does not seems to be any performance issues with the re-drawing of the rectangles.
