[](https://user-images.githubusercontent.com/13994516/71016081-eb4ca800-20f4-11ea-8fee-4d38ecfb0596.gif) Drawing curves requires two vertices. Painting areas, such as the background of a chart, likely requires four vertices. Note that vertices are not capable of featuring a style. Instead, styles are applied to polygon borders and polygon bodies. {% include important.html content="Bear in mind that the order in which vertices in a polygon are arranged around the parent polygon node when their *rotational symmetry* property is selected, is the order in which the plotter computes the points. This means that points need to be in the correct order, for example, when drawing a box. Imagine drawing a box on a piece of paper without lifting the pencil... that is how the plotter does it." %} {% endif %} {% if include.more == "yes" and include.content != "more" and include.heading != "more" %}
