How To overlay a circle on existing graph builder plot

Albatross — Mon, 19 Jun 2023 14:18:18 GMT

Hello,

I'm taking a baby step of JSL. I'd like to overlay a 150mm radius circle on the below image, which is a graph builder generated defect map example of silicon wafer. I just figured out "Circle({0,0}, 150 )" command, but it doesn't seem to work when I implemented the command in JSL script of the plot.

Could anyone help how to add a circle on it?

You could use Customize from the right click menu and add 2 Y Function scripts to draw the 2 parts of the circles:

Y Function( 150 * (Cos( ArcSine( x / 150 ) )), x );
Y Function( -150 * (Cos( ArcSine( x / 150 ) )), x );

I do this in Graph Builder:

Oval( -150, 150, 150, -150 );

Given the coordinates of -15 to 150, you are drawing a 300mm wafer

The oval may be better than the circle, see comments in (just before the giant hand) showing how the oval might not be a circle visually but matches the data space when the axes are not the same scale.

Thanks @Craige_Hales .

So, while "missing the forest", I was lucky not to play "candidate 6a".
I definitely would have got stuck after finding "circle" ;)

Nice outside-of-the-box approach I had not considered!
