A polygon is an area enclosed by a set of border lines.
Reference Polygon lets you create a reference area by adding reference lines in a graph, corresponding with user-defined values on the x-axis and y-axis respectively. The lines can be parallel to x or y axis or in any direction. Once set up, the polygon can be of any shape and will be displayed as a shadow behind the bubbles.
Use the color palette or set the code to color the Polygon.
