Drawing a fixed box in the chart

I need draw a box with text fixed in a determine point of a chart wihtout relation with the price.
Somebody knows how could i code it?

The DrawRectangle function depends on price and move with it. :/

Thank you !

You would need to do something like this :

Code

.
	public override void Plot(Graphics graphics, Rectangle bounds, double min, double max)
        {
					Brush backBrush = new SolidBrush(Color.FromArgb(backgroundOpacity, backgroundColor));
					graphics.FillRectangle(backBrush, xOffset, yOffset, longestLine, totalHeight);
					backBrush.Dispose();
					Pen borderPen = new Pen(borderColor);
					graphics.DrawRectangle(borderPen, xOffset, yOffset, longestLine, totalHeight);
					borderPen.Dispose();
        }

It is not a working sample, you need to replace the colors and the coordinates
( extract taken from jtEconNews2.cs ), but should give you a clear idea how to do
