Plotting circles in graph builder that is locked to the coordinate system

[#1]

Hi,

I am drawing too circles onto a graph builder wafer map using

Circle( {100, 100}, 100 );
Circle( {100, 100}, 95 );

in the right click in GB > customize-submenu.

But the circle is always round with reference to the pixels in the monitor. It is not really a circle with reference to the underlying coordinate system on the X/Y axis. For example I can drag the window wider and the circle will stay a circle, whereas it should become an oval as shown below.

Do you have any idea how to solve my problem?

Thanks

Try using the Oval function, which takes all parameters in data space.
