When you mention "Panel", the question is: which one? Full type name, please.
You need to tag the UI/graphics library or application type your are using, as soon as UI or graphics is involved...

Are you painting on a WinForms control? If so, you can use ScaleTransform[^]

Example (from the above page):

C#

private void ScaleTransformFloat(PaintEventArgs e)
{

    // Set world transform of graphics object to rotate.
    e.Graphics.RotateTransform(30.0F);

    // Then to scale, prepending to world transform.
    e.Graphics.ScaleTransform(3.0F, 1.0F);

    // Draw scaled, rotated rectangle to screen.
    e.Graphics.DrawRectangle(new Pen(Color.Blue, 3), 50, 0, 100, 40);
}
