Hi jthi,
Thank you very much for your feedback.
Metod 1:
Could you provide more detail steps for me, I can't plot like you.

Metod 2:
The plot appears to be perfect, but I encounter an issue when attempting to add a trend line (Actual position/ Current position). Could you please assist me in resolving this problem? Thank you.
Names Default To Here(1);
nw = New Window("Example",
Graph Box(
Frame Size(500, 500),
XAxis(Min(-175), Max(175), Inc(25), Show Major Grid),
YAxis(Min(-175), Max(175), Inc(25), Show Major Grid),
XName("x"),
YName("y"),
Pen Size(3);
Pen Color("Black");
Circle({0, 0}, 150);
"100",
ScaleBox,
{Legend Model(
4,
Properties(
0,
{Line Label Properties( {Name Label( 1 )} )},
Item ID( "Actual position", 1 )
)
)},
Pen Color("Red");
Circle({-1.865, 7.892}, 150);
"100",
ScaleBox,
{Legend Model(

{Line Label Properties( {Name Label( 1 )} )},
Item ID( "Real position", 1 )
