I'm trying to make a sort of pie-chart shape on a canvas element, however I can't seem to find any function that does this by itself. I only seem to be able to draw full circles and segments. Is there an easy开发者_如何学编程 way to do this?
(See also: Wikipedia on circle terminology)
The following should work:
context.moveTo(cx,cy);
context.arc(cx,cy,radius,startangle,endangle);
context.lineTo(cx,cy);
context.stroke(); // or context.fill()
with cx
, cy
being the center of the arc.
