The polygon render extension draws a filled (convex) polygon to the screen. This extension is only available when the polygon plugin has been loaded. Thedemonstrates how to use a polygon with dynamic point generation to render a trend graph.
The polygon render extension uses many standard options but also includes:
a list of points for the polygon (string). The list of points are x,y values that are space separated, for example: 10,20 5,5 0,0.
The style of polygon to render (string). The style corresponds to one of the following values:
|Dash ("dash")||Draw a dashed line using Fill (color) and Dash Pattern attributes|
|Fill ("fill")||Draw a filled polygon using Fill (color) attribute|
|Fill & Stroke ("filloutline")||Draw a filled polygon using Fill (color) attribute, then outlined with Outline (color) attribute|
|Line ("line")||Draw a line using Fill (color) attribute|
|Loop ("loop")||Draw a line (with connected ends) using Fill (color) attribute|
Changes width of the outline (stroke) drawn (number)
Defines the dash size and the space size between each dash, only used with "dash" style (string). For example a long line short space might look like "10 5 10 5"
Indicates if the polygon line drawn should be anti-aliased (1) or not (0).
Single width outlined polygons are not anti-aliased on OpenGL ES 2.0 platforms.
multisample option for the OpenGL ES 2.0 Storyboard runtime controls polygon anti-aliasing.
The color used to fill the polygon.
The color used to outline (stroke) a filled polygon i.e. if the style is Fill & Stroke
