Encircle a cloud of data on a plot and shade the bounded region.

How to use:

  • Right click on a data point to invoke the trace menu and select "Encircle points" to draw a polygon that surrounds all of the data in the wave.
  • If you change the aspect ratio of the plot area you can repeat this procedure to update the shape of the polygon that surrounds the data.
  • Selecting "Remove Encircled Region" deletes the shaded region.

Polygons are drawn in the user back layer using axis coordinates and can be edited with the drawing tools.
