Aligning graphics problem

I’m having a hard time understanding the coordinate system being used. 

In the following code I don’t get why my line is not drawn from the top of the rect to the bottom. 

Why does the magenta line get drawn from the middle of the rect down? 

I have anchorY = .5 and it is the same x1,y1, x2, y2 as the rect. 

local function draw\_arena() local arena\_rect = display.newRect(0,0,304,304) arena\_rect:setFillColor(1,0,0) arena\_rect.x = display.contentCenterX arena\_rect.y = display.contentCenterY local arena\_rect = display.newRect(1,1,302,301) arena\_rect:setFillColor(0,0,.3) arena\_rect.x = display.contentCenterX arena\_rect.y = display.contentCenterY local arena\_rect = display.newRect(2,2,297,299) arena\_rect:setFillColor(.3,.3,.3) arena\_rect.x = display.contentCenterX arena\_rect.y = display.contentCenterY local arena\_line = display.newLine(0,0,0,304) arena\_line.anchorY = .5 arena\_line:setStrokeColor(1,0,1) arena\_line.x = display.contentCenterX \* .75 arena\_line.y = display.contentCenterY end draw\_arena()

Add line

arena\_line.anchorSegments = true

Note: I think you should use different names for different rects.

Thank you.  

The linked forum topic is nearly identical to what I asked. I did search but I guess not well enough.  

Interesting to read the last post to it wherein the author suggests adding ‘anchorSegments’ to the gotcha in the documentation. 

That would have worked for me.
