Remove draw object line after refresh

[davidgamo]

Hi

I have one property to draw one line.

I draw the line getting the propierty value in OnBarUpdate when CurrentBar == 0.

I want to delete all the indicator's line before drawing the line, because when I change the property value and press F5 the line value doesn't refresh.

Hello davidgamo,

Thank you for your post.

Are you changing the value in code or the Indicators menu?

Hi

1) I add the indicator, and in the parameteres menu I set the propierty levels = 1953,09;1963,05;

I click OK button

Initialize()
{
string[] values = levels.Split(new char[] { ';' });
foreach (string value in values)
{
Line line = new Line(new Pen(Color.Red, 2), number, "sr" + (++count));
Add(line);

}
}

I see the two lines in the chart.

2) I open the indicator menu again, and in the parameteres I set the propierty levels = 1954,00;

I click OK button

But I see the two last lines. I have tried to delete all the lines in the chart, before the code but the Lines.Length = 0

Hello davidgamo,

Thank you for your response.

There is no method or function to explicitly remove a line that was created via the Intialize() method. You would need some sort of reset for your array. If you add the lines just using Add() and not the array or for loop you should be able to re-adjust the lines.
