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
