CCNA, CCNP, MCSA, CCNA Final Exam, All Answer Test Module With 100/100

I just started with fabric.js and I have a (probably beginner) error: I am using fabric with jquery with the following code: $(document).ready(function () { canvas = new fabric.StaticCanvas('scroller'); canvas.add( new fabric.Rect({ top: 0, left: 0, width: 140, height: 100, fill: '#f55' }) ); }); This code should draw a 140x100 Rectangle on the canvas. Sadly, only a quarter of the Rectangle appears. If I change the top and left values to higher numbers, more of the Rectangle appears on the canvas. So it seems, that the canvas origin is not at 0/0, but at sth. higher. Does someone know how to fix this or what I am doing wrong? Thanks in advance, McFarlane
