Is there anyway to get the (x,y) position of where a data point from a DataSet was plotted
in the plot area? I want to draw a circle around certain data points to draw attention to
them. Like the attached picture.

Nevermind. I found the layer.getXCoor(j) and layer.getYCoor(data3(j)) functions. They
work wonderfully. See attached.

Hi Patrick,
The method I usually use is to add symbols to the special points using a scatter layer. The
symbol can be a circle with transparent fill color and a red border color.
