DrawEllipse with no markers on Line

Hello

I would like to have an ellipse on my scatter plot (not an image) that I am creating with the scatter function. I would like to enclose certain data points with an ellipse.

I tried two ways:

1. inserting an ellipse from the interactive Figure window. However, I cannot make it transparent (no FaceAlpha)
2. using drawellipse from the Image Processing Tool Box. This works very well, except that the 4 markers show on the ellipse line. I changed the MakerSize to 0.1 and this helps but they are still visible and can be confused with actual data points from my scatter plot. I was wondering if there is a way to show the ellipse with no markers on the line.

Thanks!

See attached demos where I put ellipses on graphs with no handles. One of them should do what you want.

Thanks for that. However, it is not what I was looking for. I am using the drawellipse function (https://www.mathworks.com/help/images/ref/drawellipse.html). And it works well except that the markers of the ellipse show as seen in the left panel in figure attached.

I just found how to do it: this should be added to the Tips section of the Ellipse Documentation:

Position the pointer near a vertex. The pointer changes to the rotate pointer. press Shift and Click. Markers will dissapear and image can be copied with ellipse (and no markers).
