Draw rectangles

Highlighted
Hi!
 
I'm using Measurement Studio 7.1.
I have the problem to get a rectangle into a graph which shows
measurement data.
This rectangle should be as scrollable and zoomable as the
graph but my rectangle i insert is fix on the screen.

e.Graphics.DrawRectangle(

new Pen(Color.Turquoise,2),10,10,50,50);//   works!!! but without scrolling and zooming

 
Hope you can help me.

Are you using the rectangle to highlight a region of data? Have you tried using a range annotation instead?
To add a range annotation, right click on the graph, select "Edit Annotation..." and then in the collection editor, select Add >> XYRangeAnnotation.

This should take zooming and panning into account.

I hope this helps

Thank you for reply.
It is a little bit of that i want to have.
This rectangle 'window' should be able to move and
edit(runtime), something like a rubberband rectangle.
I need this for my measurement data graph in which i
will insert this window to control if my graph is in this range.
Hope you understand me.
 
Seconde Question.
How get I single lines in my graph which are also can be moved and
edited?
 
Thanks

This is my result. All I want works, but it is very inexect in the area auf the

edge points. Can anyone help me?

Another Problem is to use this one outside, i.e with a ButtonClick.

 

 

PointF point1 = e.Plot.MapDataPoint(e.Bounds, 1.0, 1.0);

PointF ZeroPoint = e.Plot.MapDataPoint(e.Bounds, 0.0, 0.0);

PointF point5 = e.Plot.MapDataPoint(e.Bounds, 1.0, 1.0);

Point point6 = new Point(Math.Abs((int)point5.X - (int)ZeroPoint.X), Math.Abs((int)point5.Y - (int)ZeroPoint.Y));

Size mySize = new Size(point6);

Point point7 = new Point((int) point1.X, (int) point1.Y);

e.Graphics.DrawRectangle(new Pen(Color.Turquoise,3), new Rectangle( point7, mySize) );

Could you attach a sample of your app? It'll give me a better idea of what the problem might be

Thanks
