Draw Oscilloscope line chart on a Windows Form

No there is not, unfortunately.  Why don't you create an image in memory, and draw on that?  Then you have a PictureBox object on your form that you can set to display your image every time you add a point.  The PictureBox would then have scroll bars.  Or create a custom control that you will draw to instead.

But what I am really wondering is why you don't just size your output to the form's current size?

it can be done. i did the exact same thing. i didn't want to resize or distort the graph.

i used a panel within a panel, and drew on the child panel. if the x coordinate was greater than the width, i increased the child panel's width to the x value. and i set the parent panel's autoscroll property to true.

It sounds like a good idea, msdixon. However, when I move the scroll bar, the line changes its length. it becomes shorter than the original one.

you will see the same effect if you try the following code.
      
Graphics g = panel1.CreateGraphics();
Pen myPen = new Pen(Color.Blue);
myPen.Width = 2;
panel1.Width = 2000;
pnlCanvas.Refresh();
g.DrawLine(myPen, 0, 50, 2000, 50);

Thanks a lot

This is to eternal_21,

How do you draw a line on a System.Drawing.Image object? Can you provide more detail?

Thanks.
