Removing Draw Text?

[woodyfox]

Could some help me with this. I'm trying to remove the last draw text! It will draw the the text, but can't seem to remove it?

private int lastPBar = 0;
private int thisPBar = 0;



if (CurrentBar ==0)
return;
if(PU[0] < PU[1])
{
if(PU[0] == 100000)
lastPBar = 0;
else
{
lastPBar = thisPBar;
}

thisPBar = CurrentBar;

Draw.Text(this,"PUp"+CurrentBar.ToString(), true,"P", 0,
Low[0]-LabelOffset*TickSize,0, Brushes.Green, trifont,
TextAlignment.Center, Brushes.Transparent,
Brushes.Transparent, 1);
if(lastPBar >0)
RemoveDrawObject("PUp"+ (CurrentBar-lastPBar));
}
Thanks,

Hello woodyfox,

I'm not certain that I am understanding.

Are you trying to draw an object and then immediately remove that object on the same bar?

If you print the string you are using does this match the tag name of the drawn object?

(Likely the CurrentBar value is changing)

[woodyfox]

No, the last draw.text under same tag

Hello woodyfox,

With the code provided it appears that the Drawing object will be removed on the same bar it is drawn on if lastPBar is greater than 0.

Please provide the output from the prints.

What is the output from the string used for RemoveDrawObject?

What is the tag of the drawn object?

Hi Chelsea, Could you be so kind to provide an example where a bar value is stored at CurrentBar and then can be referenced at a later time? (to remove draw.text) Im hoping there is an existing indicator I can use as an examlple.
Thanks,

Hello woodyfox,

Unfortunately, I am not aware of a specific script that has custom logic to remove drawing objects by storing the CurrentBar number.

[woodyfox]

OK. Any hints, Tips, etc. Someone has had to ask if its possible to remove prior bars Draw.Text. Any examples on forum. Any help would be helpful.
Thanks,

Chelsea,
Disregard last entry. I figured it out, my code had a small mistype. Thanks anyway.

Hello woodyfox,

Its always helpful to debug the code by using prints. This would be the fastest way to fix the code to what you are wanting.

Below is a link to a forum post that demonstrates using prints to understand behavior.

After some research I found the AutoTrendHNT8 indicator included with the AutoTrendHDemoNT8 strategy on the forums stores bar numbers and uses this to remove drawing objects.
