drawing bar

[julifro]

hello. I have a code that when a condition is met it paints the bar with a color. All the bars where the condition is given are painted and that slows down my computer. How can I make it paint only the last bar where the condition occurs? thank you

Hello julifro,

If you re-use the tag name, this will move the drawing object instead of drawing a new object.

You can avoid drawing objects in historical data.

if (State == State.Historical)
return;

You can remove older drawn objects by their tag name with RemoveDrawObject().
