Reference Circle in Scatter Chart

I have a chart like Image-1 I want to add a couple of reference circles to it and make it look like image 2.

Appreciate any help!

Maybe just use an image as frame background (on Colors tab, AFAIR)?

Reference circle radius should be dynamic.

Hi,

you could add two expressions to the chart (if it's a line chart) for a circle.

But you need a numeric X-Axis

1. Circle half top

    sqrt(pow(vRadius, 2) + 0.000000001 - pow(X-Axis, 2))

2. Circle half bottom

    -sqrt(pow(10, 2) + 0.000000001 - pow(X-Axis, 2))

Or, if you need an ellipse use this expressions

1. Ellipse half top

     Sqrt(Pow(vRadiusY, 2)*(1-Pow((X-Axis), 2)/Pow(vRadiusX,2)) + 0.000000001)

2. Ellipse half bottom

     -Sqrt(Pow(vRadiusY, 2)*(1-Pow((X-Axis), 2)/Pow(vRadiusX,2)) + 0.000000001)

(See attached .QVW)

Otherwise I think this is not possible.
