class anychart.graphics.vector.Circle Improve this Doc
Extends: anychart.graphics.vector.Ellipse
Circle Class. Inherited from Ellipse.
Do not invoke constructor directly. Use anychart.graphics.vector.Stage#circle or
anychart.graphics.vector.Layer#circle methods, if you want to create an instance of primitive bound to a stage or a layer.
In case you need an unbound primitive - use anychart.graphics#circle.

- ObjectBoundingBox with angle value preservation
- ObjectBoundingBox without angle value preservation
- UserSpaceOnUse
Modes:
ObjectBoundingBox without angle value preservation (the first rectangle on the image)In this mode the result angle will visually correspond the original setting, non regarding browser scaling duplication (so, for objects that do not have 1:1 proportion with the original figure, the gradient angle will correspond to the initial value due to internal calculations).
ObjectBoundingBox with angle value preservation(the second rectangle on the image)
In this mode, gradient vector is calculated with the preset angle, but the result gradient angle on the rendered page can be changed if the object proportion is not 1:1 in the browser. So visually the result gradient angle may not correspond to the original settings.
UserSpaceOnUse (the third and fourth rectangles on the image)
In this mode gradient settings are added by gradient size and borders/coordinates, and rendering is calculated within those borders. After that, the fill is executed on the element figure according to its coordinates. More about this mode at gradientUnits.
